Re: routine declaration line question

If a routine does not declare it's return type, absolutely anything can be returned. One reason may be that its return value isn't really useful. It could be that the writer didn't think to declare it. (or didn't want to) Another possibility is that the potential returned values are of many

Re: routine declaration line question

I just spotted a grave mistake in my earlier mail: the --> constraints are validated at *run* time, not *compile* time; that's a very big difference, and an important one. Of course "every time a sub or method returns" doesn't make much sense if i had meant "compile time", but I felt i should

Re: routine declaration line question

_All_ routines in Perl 6 return _something._ A lack of a "-->" simply indicates stylistically that the return is not useful because it's whatever "falls off the end". (There's a bit of variance here as I'm not sure it's a convention everyone has followed.) It's equivalent to "--> Mu" because

Re: routine declaration line question

Perl 6 routines always return *something*; if you don't return anything explicitly, it will return the result of the last statement/expression, or Mu as a last resort. (Mu is the "least defined value" in Perl 6. Any is somewhat more common, but is slightly more defined since it can participate in

Re: What are the official names?

Thanks for the feedback. Note that this is also a routine declaration: sub postcircumfix:<[ ]> ($lhs, $inside) { ... } The term "name" is ambiguous. I guessed you might mean it generically, so that's why I started with "routine declaration". But "name" has a more specific meaning in Perl 6 so

To simplify, it is my understanding that the "Apocalypse 6: Subroutines" document define that as a subroutine declaration, with signature. Forgetting the nomenclature, that might well be inspired by magical imaginary, AFAIK, it is practically just pattern matching, same as a regex: to teach the
