How?  /usr/bin/if?  What's wrong with that?

Pleas name at least two.  And show example of your so-called "interferention".

According to SUSv3, "if" is a reserverd word. "Reserved words are words that
have special meaning to the shell".  It is not even a builtin.

Care to show some examples, how /usr/bin/goto "breaks everything"?  Or maybe
you want to take over this review?
