Developers cannot live without it.

Hmm... Birdy and colonel... Why am I thinking of Michael Caine in 'The Eagle Has Landed'?

A film about Germans. You should never mix Germans and Golf, they always end up in the Bunker.

And here's me thinking Golf was German :doh:

Dalek Dave

This[^] is German. This[^] is Scottish.

Aah yes... The second one is definitely not German as it is missing trenches... Which gently brings me to an episode of Fawlty Towers. John can sure swing his legs about in the air.

That's a very wise decision. Lua is a meta-language. Any meta-language MUST provide goto - otherwise implementing higher level constructs could be too complicated.

No, I'm 100% serious. A typical example: implementing a high-level eDSL for, say, generating a Packrat parser out of the PEG grammar. The most straghtforward translation scheme will involve making a function for each terminal, with a single "failure" label at the end, and all the failed sub-expressions will just goto there. But for a target language without a goto, a compilation scheme would be significantly more complicated.

CPallini

That's just a 'lack of goto' problem. I cannot understand why you define Lua 'meta-language'. Furthermore, in my opinion, it is a complete (and fairly powerful) language.

In BBC BASIC "On Error Off" is used to turn off any error trapping. In Visual Basic "On Error Goto 0" is used to turn off error trapping. But it doesn't go to line zero when an error occur it displays a message and exits the program. So the GOTO command survives but doesn't go to the line you asked it to goto.

On Error Go To Bed :)

It's an OO world.

public class Naerling : Lazy<Person>{
public void DoWork(){ throw new NotImplementedException(); }
}

public class Naerling : Person{
public void DoWork(){ throw Unknown(); }
}

FFY. :)

Unknown is no function or property I implement. Though I am lazy I still want to compile ;)

It's not unlike the double-negative in English -- it's only bad when you use it wrongly.

I wanna be a eunuchs developer! Pass me a bread knife!

You may say the same for (say) threads, still... :)

There is an eval - so, it is a meta-language, at least to the same extend as JavaScript 2) I use http://metalua.luaforge.net/[^] which is a "true" meta-language It is very powerful indeed. But the languages lacking the goto statement are not very good compilation targets.
