Well. Their expectation simply does not work *at all* because they do 
something (setting SIGFPE to SIG_IGN) which is completely ignored on at least 
one major platform (x86 linux) for longer than it has git history.

Their math code seems to work around generating such errors, but I find it 
rather hard to read (or rather read & understand).

Doing what I proposed admittedly has the issue that we would jump out of perl 
code without much ado. I have no idea whats the proper perly way to do so is.
It just seems we should do something...

if (in_perl)

Would be the equivalent of what they want?
