I also noticed this after some quick testing and just sent a v2 right before

Your (untested) implementation seems much cleaner than mine, and I'm happy
to give that a try. Question: is it okay that we pass just a raw command
name to exec instead of a full path? That is, is there any reason we need to
first find the command in PATH *and then* pass it to exec (which is what my
v2 implementation does)?

I don't think so. Perl's exec() should do the PATH lookup itself. I was
surprised not to see this mentioned explicitly in the documentation, but
it clearly does work. E.g., try:

  perl -e 'exec("ls")'
