in reply to Perl "Constants"

If you want to continue using constant, and you want to interpolate within a string, the only way I know of is using the array interpolations:

use constant SOME_CONSTANT => 'the value';
print "This is @{[SOME_CONSTANT]}\n";

Within a hash key, treat it as a sub:

$h{&SOME_CONSTANT} = 'hash value';

    For string interpolation you may also use scalar context 

    print "This is ${\SOME_CONSTANT}\n";

    With a hash key you can also disambiguate a constant with parens 

    $h{(SOME_CONSTANT)}
