That is a different topic, not related to exceptions at all.

Confuse which people? Do people now are confused that you can write
multiple catch clauses for same exception but can't write multiple
function bodies for same parameter set? Are they confused by the fact
that it's a fatal error to pass wrong type to a function but catch just
silently ignores it? Are they confused that you can write
function(string $a) but you can't catch(string $a)? I don't think so. I
think people are pretty good at figuring out exceptions and function
parameters are different things. Java has multiple catch and no
expression types, and .net has the same after a fashion (with somewhat
weird syntax) but programmers on neither wonder around confused
expecting to find type calculus somewhere.
