    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
        I see... Maybe "smart matching" promises to do too many things...
