Straight from the examples in Quantum::Superpositions

use Quantum::Superpositions;
 
if ($x == any($a, $b, $c)) { ...  }

IIRC this is implemented by `any` returning an object overloading the `==` operator. And there is maybe also `tie`'ing involved. Hence many movable and slow parts. Essentially a very sweet syntax coming with a cost. Question: is there also intelligent support for ranges? I'd buy into this if yes. like `if ($x == any(1,2,5,6,9,10,[41,56]) { ... }` ? I suppose it's clear where the advantages are ... Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

No clue, although I completely glossed on the range requirement in the OP. Having seen that I'd change my answer to Set::IntSpan probably. The cake is a lie. The cake is a lie. The cake is a lie.	[reply]
