If I were to create something like 
use constant TEST => 'def';
my $string = 'abcdefg';

if ($string =~ /TEST/) {
   print "The string contains the constant.\n";
}else{
   print "The string doesn't contain the constant.\n";
}

It's awfully hard for the interpreter to know that TEST is actually a constant, because to the regex engine it's just another string. The /e modifier doesn't work. Is there a way to do this?
