h(re) for help, import re - on NameError

[Veek M]

Is there a way to use .pythonrc.py to provide a help function that 
autoloads whatever module name is passed like so:
\>>> h(re)

I tried inheriting site._Helper and overriding __init__ and __call__ but 
that didn't work, also I don't know how to deal/trap/catch the NameError 
(no quotes on h(re)) - is there a way to insert a try/except block 
around the >>> prompt?

I hate having to: import whatever every-time i forget. Actually could I 
ditch the () in h(re) and just do: h re - the joy of that :p
