dynamically creating variables

I am writing a parser and I have a routine that can digest
a series of tokes:

def digest(*args)

I use it like this: digest("FOR", "IDENT", "EQ", "INTVAL", "COLON").
This part works fine. My digest function returns a list of the values
associated with each token.

  dummy1, ident, dummy2, start = digest("FOR", "IDENT", "EQ", "INTVAL",
"COLON")

But I dont like the way this looks and I want my digest routine to do
more work. I want to be able to specify the variable bindings in the
call to digest - and not have them be on the LHS of the assignment.

Ideally I want to call digest like this:

digest("FOR", ("IDENT",ident), "EQ", ("INTVAL",start), "COLON")

and have ident and start be local variable defined in the place that
calls digest.

Is it possible to do something like that?
