That has the large drawback of declaring that "foo" is the same as "cheesecake" (while emitting two warnings). :)

In my particular application, a foo is indeed the same than a cheesecake!

    Then use $a == $b. The $a eq $b || is just obfuscation. The only thing it changes is that it prevents warnings when given two equal, non-numeric strings (because if $a eq $b, then it will also be true that $a == $b).

    Then all you need is 
    my $result = do { no warnings 'numeric'; $x == $y };

      I had not thought about using a do block. Thanks a lot - this is an elegant solution!
