Maybe `!($a cmp $b \|\| $a <=> $b)` would work... nope. -Paul	[reply] [d/l]

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! -- Ronald Fischer <ynnor@mm.st>	[reply]

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`). - tye	[reply] [d/l] [select]

Then all you need is `my $result = do { no warnings 'numeric'; $x == $y };` [download]	[reply] [d/l]

I had not thought about using a do block. Thanks a lot - this is an elegant solution! -- Ronald Fischer <ynnor@mm.st>	[reply]
