point notation

[Markus Endres <me@mendres.org>]

hallo,

I'm going to write a routine called GrInit which initialize a group ring
K[G] (like nfinit or bnfinit) in some way, returns something like the
wedderburn decomposition, K-irreducible characters, the maximal order
and something more. 

now, I want to use the point notation as in nfinit/bnfinit. that means,
I want a possibility to call my results like K.disc in K=nfinit(pol), as
example: KG=GrInit(...); KG.Kchi; which returns the characters 

This point notation would be very useful for me. Is there any
possibility to write such a 'point notation' by my own?

thank you very much

Cheers
