Most head-slapping feature in a language
-
@Forogar and I were having a chat about unintended programming features (ahem) due to things like: Javascript's truthy:
"1" == 1 is trueRexx:" Hello " == "Hello" and 0.0 == 0 is not the same as 0 == 0.0SQL:Len("hello") = Len("hello ")I'm just wondering what other family favourites there are out there. (Edited because clearly I’ve lost track of what’s up and what’s down)cheers Chris Maunder
erm, typo?
"1" === 1 is false
"1" == 1 is true (truthy rather) -
Officially, I actively choose to not slap myself becuz of a (programming) language's nuance(s). :doh:

Re-read the OP. Chris didn't state he was going to slap his own head .... :laugh:

In Fortran (at least in the old days, Fortran IV and thereabouts) has no reserved words. Spaces have no significance. So you could declare a variable named INTEGER REAL INTEGER INTEGER = 3.14 or a subroutine named FUNCTION to be invoked by CALL FUNCTION(...) The standard loop construct is the DO loop, but DO U BLEP RECISION IF is not the start of a loop. Rather, you could make a comparison with the above variable IF (IF.GT.INTEGER) ... In my student days, there was a single course teaching Fortran. We made it a habit to solve the execizes using predefined identifiers only. Sort of like OCCC, but it took far less effort to obfuscate Fortran.

The point of === is that "1" == 1 but "1" !== 1, that is, "1" === 1 will return false, due to the differing types
This is the kind of crap you get in a weakly typed language.

In the old fortran stuff: 3 = 9 And change the value of 3 to 9 (Because some nimrod decided to declare numeric constants as variables?) LMAO. But they fix everything by adding an =, so we get =, ==, ===... I am waiting to read some code:
if (x ======= y) // equal on 7 planes of existence
and
if (x ======== y) // A fuzzy version of the above allowing for LESS Equality to be Equal, LMAO

Y'all need to re-read my comment. Never did imply nor explicitly express Chris did or would do that. :doh:

I just loved seeing C/C++ code from colleagues too lazy to comment out a block of code (and letting it sit there for years) via: #if 0 ... #endif I should just go back to clean it out, but now it's nostalgic for me. :-)

Wait 5 years. It will be:
"1" ============== 1
As in, "I really really really really really really really really really want to know if it's really really really really really really really really somewhat mildly truthy."

I had a colleague who insisted on occasionally writing the (perfectly valid but ummm counter-intuitive) form
index[array]
in C. He also worked out some multi-dimensional extensions, which my marginal brain is too small to contain. And yes, he did have a shot at the The International Obfuscated C Code Contest[^] Cheers, Peter

Yes, I was (long ago) proudly shown char c = i["Some string"];

I had never thought about pointer arithmetic being commutative before... seems consistent at least. int index = 1; char *address = "String"; index[address] is the same as *(index + address) address[index] is the same as *(address + index) + implicitly includes the size of the base data type. (char) If this was attempted with variables instead of constants, you might end up with memory protection issues. Most OSes would not want you to start a loop by loading memory address 1 into a register. They would let you load the memory address of "String"

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

I remember being frustrated by the fact C# 1.0 had a default container called ArrayList. Is it an Array, or a List? These are very different things. Is it a fancy container that somehow has worked out how to get the benefits of both? The documentation never said.
