If by "something truly dumb" you mean "equalness might fail due to rounding issues"
that ain't Perl, it's a function of performing "real" arithmetic using finite precision and is unavoidable (most numbers can't be represented using finite precision).
Why the down votes? I don't know, but it may be people are assuming you didn't read Why do floating point numeric equality/inequality tests fail mysteriously? and the material linked from that node and said something "truly dumb" in consequence. ;)
Perl's payment curve coincides with its learning curve.
