Thats because aliases don't do arguments and function do. In fact,
AFAIK, any bash construct works in a function so they can be quite
involved and flexible if you want.
An rpm enhancing function from the bash_completeion proejct that
does tab completion of command line:
# rpm(8) completion

_rpm()

local cur prev

cur=${COMP_WORDS[COMP_CWORD]}
prev=${COMP_WORDS[COMP_CWORD-1]}

You might check your environment (ie set), RH probably has some functions already defined.
