It's not necessary to delete a function definition before replacing it, but
there is a point to removing an alias before defining a like-named function.
So the keyword you're looking for is "unalias", not "unset".
If for some reason you absolutely must have an alias and a function with
the same name, consider forcing parsing of the function before the alias
command is executed:
{ alias foo=bar; foo() { echo this is not Bar; }
or use a ksh-style function definition:
alias foo=bar
function foo { echo this is not Bar; }
(note the lack of () in the latter form)
