Completion on non space separated words

[nlewo]

I would like to bring completion on a language where words (or lexical identifiers) of an expression are not separated by spaces. For instance, consider the following expression:

object.method(value)

where object can have several available methods.

I would like to be able to do

object.<tab><tab>

to get the list of method and select a method among this list.

Is it currently possible? And is there an example somewhere?
Thanks.
