st: strip factor variable operators?

[Stas Kolenikov <skolenik@gmail.com>]

Dear statalisters,

is there a simple way to strip out the time series and factor variable
operators? I have a list of regressors with all sorts of stuff like
-i.foreign ib3.rep78 c.price##c.price-, and I want to produce a list
that is cleaned off the prefixes, just -foreign rep78 price-. Is there
a standard parser, or an extended macro function, to do this? I can
take the whole list, -gettoken, parse(".")- each term and strip the
part before the dot, if there's any. But this seems like a relatively
mundane task that must be doable with some official Stata tools.
