EXAMPLE:
my %hash = foo => 1;
if %hash<a>:exists {
say "not gonna print this";
}
my $key = 'b';
if %hash«$key»:exists {
say "why i'm here";
}

OUTPUT:
why i'm here

EXPECTED RESULT:
(Should not print anything)

FROM #perl6 CHANNEL:
14:09 < masak> m: my %hash = foo => 1; my $key = 'b'; if
%hash«$key»:exists { say "why i'm here" }; say "alive"
