bit operations happen normally on unsigned integers, I'd say in >90% of the cases (at least)

And I've already shown two instances of perldocs demonstrating exactly that pattern.

> in a PV ? in an IV ? in an NV ?

I reckon IV is an integer value ... please explain the rest° in this context, my perlguts are aching ;-)

And the OP will most probably only know "scalar".

°) OK looking up in "Advanced Perl Programming" (sic)

> A scalar value (SV) contains the value of the scalar, a reference count, and a bitmask to describe the state of the scalar. The scalar may be an integer value ("IV"), a double ("NV"), a string ("PV" for pointer value),

I can't see how this is relevant here.

update

I mean: If someone asks how best to hold a hammer, do you complain he didn't tell you which alloy the nails are made of and where the original ore was mined? Seriously?
