Hello,

Are there any hooks for defining autocompletion for my own functions? Suppose I have  
`func(enum::Symbol)` and I `enum` can only have values `:foo`, `:bar` and `:baz`, is there a autocompletion hook somewhere in julia base that I can define such that after typing `func(:` in the REPL, `\t` will suggest `:foo`, `:bar`, and `:baz`, and autocomplete up to the point of ambiguity?

Thanks
