Re: Perl6: S2 identifier and $ special var questions

[PrakashK]

in reply to Perl6: S2 identifier and $ special var questions

In S02 synopsis, section "Names and Variables", I see:

$<foo>      match variable, short for $/{'foo'}

So, when you say my $<-var>;, you are actually initializing the key -var of the hash $/.

Here's what I see in recent rakudo:

>> perl6 -v

This is Rakudo Perl 6, version 2011.07-2-g1b7dd12 built on parrot 3.6.
+0 RELEASE_3_6_0

>> perl6
> my $<-var> = 42
42
> $/
-var    42

> $/.WHAT
Hash()

Thanks, the code is explained.

How would I declare and use $MyClass::-O'malley's as indicated by the quoted spec?

Be well,

You may not start an identifier with - like that; hyphens and apostrophes are only allowed internally.

In theory one can declare or use any name you like using Perl 6's explicit symbolic ref notation:

    my $::("-O'Malley's") = 42; say $::("-O'Malley's");

However, neither implementation does constant folding well enough yet to recognize these as a static variable names.
