scalar ref as hash value
Raw
scalar-ref.txt
Given this Perl 5 script which allows a scalar reference
as a hash value:
#!/usr/bin/env perl
my $b = 0;
my %h = ( a => \$b );
my $b1 = ${$h{a}};
print "\$b1 = $b1\n"; # output: 0
$b = 1;
$b1 = ${$h{a}};
print "\$b1 = $b1\n"; # output: 1
What is an equivalent Perl 6 script to bind an in-scope variable
to a hash key?
