use in the body of a function, but define the function first if the
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(

+ Adding the quotes has no effect on the function definition, but
+ suppresses alias expansion for the function name. Hence this is
