( #3333=superdoc: print w/ replies, xml ) Need Help??

As long as you're going to go through the same code path for each element in the array anyway, why not de-obfuscate that a bit and use the ternary operator?

if (1 == sum( map { $_ ? 1 : 0 } @inputs ))
While tye may be right that, in practice, Perl can't change the value of !0, I just don't like relying on obscure implementation details when clear, well-defined implementation details are available to me to accomplish the same thing in a readable, understandable, and maintainable manner.
