! $this->isa("pipe")

Syntax is correct, though it will die in runtime because $this is not declared.

If you're worried about errors, I recommend instead: `! UNIVERSAL::isa($this, 'pipe')` Just in case there's a possibility that `$this` might be undef, or an unblessed scalar.	[reply] [d/l] [select]

For poetry, I'm not worried about it. Syntax correctness is all that matters, and putting `UNIVERSAL` in there just adds clutter. "There is no shame in being self-taught, only in not trying to learn in the first place." -- Atrus, Myst: The Book of D'ni.	[reply] [d/l]

I think an easier way to prevent it from die-ing, would be to change that to: `!this->isa('pipe');` or `this->isa(!'pipe');` is another possibility. I agree the `Universal::` just add clutter. Gyan Kapur	[reply] [d/l] [select]
