It is not a drop-in replacement for test; it is syntactic sugar for
compound test operations. If you're concerned about this, add a test
before the loop to ensure that there are only two arguments to the function
and restrict it to that syntax option only.

It's not as good as multiple test commands: test -f file && test -x file.
There's no ambiguity and you get short-circuiting.
