Unicode variable names

Perl 6 is written in Unicode so, with narrow restrictions, nearly any Unicode letter can be used in identifiers.

See Perl 6 Synopsis 02. - http://perlcabal.org/syn/S02.html#Names

my $Δ = 1;
$Δ++;
say $Δ;

Function and subroutine names can also use Unicode characters: (as can methods, classes, packages, whatever...)

my @ᐁ = (0, 45, 60, 90);
 
sub π { pi };
 
sub postfix:<°>($degrees) { $degrees * π / 180 };
 
for @ᐁ -> $ಠ_ಠ { say sin $ಠ_ಠ° };
 
sub c͓͈̃͂̋̈̆̽h̥̪͕ͣ͛̊aͨͣ̍͞ơ̱͔̖͖̑̽ș̻̥ͬ̃̈ͩ { 'HE COMES' }
