$var ~~ [qw/foo bar/];

carefull! better always stringify if you're not sure that its not a ref `"$var" ~~ [qw/foo bar/]`	[reply] [d/l]

Why, with the following expected behavior? `use Modern::Perl; my $var1 = 'foo'; my $var2 = \$var1; say $var2; # prints SCALAR(0x2590b8) say "$var2"; # prints SCALAR(0x2590b8) say $var1 ~~ [qw/foo bar/]; # is true: prints 1 say $var2 ~~ [qw/foo bar/]; # is false: prints nothing say "$var2" ~~ [qw/foo bar/]; # is false: prints nothing` [download]	[reply] [d/l]
