Hmm. Neat. I had not realised that was available.

You'd need "vars.keys()", not "vars", for the first use of "vars", BTW:

  return namedtuple("locals", vars.keys())._make(vars.values())

A remark for the OP: a method name like "_make" would normally be something you 
would avoid as it is Python convenion that _* names are "private", which in 
Python usually means subject to arbitrary change and probably not documented; 
internal implementation mechanisms as opposed to published interfaces.

However, in namedtuple the word "_make" is chosen specificly to avoid clashes 
with the "named" tuple values (which would normally not start with "_"), and it 
is explicitly documented.

Thanks Peter!

Nothing is impossible for the man who doesn't have to do it.
