in thread Comparing a value to a list of numbers

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 ...

    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.
