One of the reasons we don't see it often is that $_ is usually used in a context close to where it's set. So we see it used inside foreach loops, inside of <> constructs, etc. Usage of $_ is rare (in my experience) outside of an explicit context that sets it. You'd have to be calling a subroutine that modifies $_ without providing a context that sets it to have a problem like this.
