Programming's Foul Language

I like writing documents. :)

.... right up until something changes in the library and it can throw a new exception at which point the library author has to either break every single app that consumes it, cast the new exception into a different type defeating the purpose of typed exceptions in the first place, or just have every method throw exception from the start defeating the purpose of checked exceptions from the start.

That might happen even if you don't have typed exceptions. And we will always have the option of handling a base exception, which covers all exceptions for cases like this.

This is the only thing about JAVA that I miss wish to be in C#. This is very useful when you're using other people's libraries. You get know what to catch, without needing a very well documented library.
You do realize you can mark up which exceptions are thrown in XML comments? I forget if that junk shows up in the intellisense though...

Amen. Any language that uses VB6 style exception handling should be outlawed. Gives me a headache every time I try to read it.

What programming terms would you consider equivalent to foul language? For example: Legacy Code

Spagetti code. "Budding" code. "Moulded" code (large sections commented out). Quick fix X|

Kidding ? :omg: Coding without it is like using FORTRAN: do not catch anything, or enclose all code in try/catch, just in case ;P

Drop the semi-colon? And be forced _ to resort to VB's _ horrible style of _ line continuations!?!? No thanks. Though the case sensitivity... I wouldn't have to deal with code where people name the private variables the same as the exposed properties, with just case differences... Or better yet, gems like:
int num = Num + NUM;
Thankfully, I've never actually seen a line that bad, but imagine a program written like that... There's something you can't do in VB.

GOD, I FUC^N HATE THAT and they do it in textbooks, tutorials, samples --- yeah that's right Microsoft I'm talking to you.... I propose anyone caught doing this gets paper cuts on the tips of all of their digits... that will teach them. (try typing now you sick B@$$+@rd$ I slept last night so i feel good today, try me again in 24 hours I won't be so plucky.

I agree with that, despite knowing that at Assembly level, that's exactly what your code will do.

goto can actually be useful (if used extremely sparingly - so sparingly that I haven't used it in over 10 years!) One example where goto is very helpful is in programming an efficient state-machine. Oh, I know you can do it without gotos by using functions and/or block escapes, but the goto is much more efficient -- and, in the case of a state-machine, actually HELPS understanding of what is going on.... FWIW (getting ready for all the thumbs-down).

I guess I'm not saying that they can NEVER be useful, it's just that whenever I've seen it used abused, it had no business in the code and it's always at least a red flag.

Valid point, but if your library is very volatile, you can wrap all exceptions that happen in your method into a YourCustomException and throw the wrapper instance.

Oh yeah! ALWAYS a RED FLAG! Even when I did have to use it (in the large state-machine) I felt dirty and wanted to run home and take a shower every time I looked at it. After numerous code reviews (some by the VP of development), it held up as the most efficient way to handle the data stream. And, it's in the comments/documentation for the code.

Yes, it does.

One defense for the goto I've heard is from people whose programming policies require that functions have a single exit point. Aiming for a single Exit Sub/Function/Return point without goto can easily make for some complex and hard to maintain control paths, often with multiple levels of nested if/then blocks.

Prolific maybe, but between them and partial classes, I get quite extended.
Oh, yeah, I forgot about
partialwhen I wrote that, but then I usepartialeven when I don't need it. I actually feel that classes should bepartialby default and that there should be no keyword for it. Trying to compile an actualpartialclass with C# 1.0 will break even if there is no keyword, so I don't see the need. And I think the word I really wanted was "profligate"; I'm not sure which word works best in the context. -
