I was recently trying to work with Metalhead - the particular module is not important. I wanted to find all the functions exposed by Metalhead.  
In the ? help prompt I found that:

?Metalhead does nothing  
?Metalhead. does a tab complete and shows the functions

Woudl it be easy to change the behaviour?

This is the same as in the normal REPL mode. I think the current behavior is fine (and consistent with tab completion in other systems). If you want to find the symbols in a namespace, write `namespace.` and press TAB?

@kristoffer.carlsson My point is that you have to somehow ‘know’ to add the . character.  
This is not a big beef. If this is the same as on many other systems I will shut up.
