alias has the same name as the function. alias has the same name as the function.
If you aware of the problem, you can always escape part or all of the
name of the function:
verb(
'l'() { /bin/ls -la "$@" | more }
)
Adding the quotes has no effect on the function definition, but
suppresses alias expansion for the function name. Hence this is
guaranteed to be safe.
