in reply to Re: Re: Re: my, my, my
in thread my, my, my

There's already example code out there with σ as an operator-sub, in exgisis 1, IIRC, so that will almost certianly work. I suspect the rule will end up being different for op-subs.

And I'm fairly certian that p5 allows arb. unicode var. names, but not subnames, but I don't quite recall... I'd test, but I'm not at home.

    Unicode sub names are fine.

    But, I discovered something else: my doesn't work right. With strict, I get an error that "global $α requires explicit package name" on the line that declares it lexical!

    Without strict, it compiles, and the other code shows that it is indeed lexical.

    #use strict;
use warnings;
use utf8;

my $α= 5;
my $Φ= 4;

sub Φ
 {
 return $Φ;
 }

package XX;
$main::Φ= 33.33333;

package main;

print Φ;

      Here's a twist. Under perl 5.8.0, compiled for cygwin, you program works fine if and only if use strict; is present.

      On the other hand, if use strict is commented out, I get this bizarre error:

      "my" variable $strict::VERSION can't be in a package at lib/strict.pm 
+line 93, near "$strict::VERSION "
Compilation failed in require at lib/utf8_heavy.pl line 2.
