Sorry, I was unclear about the fact that the args are formals. I'm
trying to do something like:
func = "dothat"
args = ('x','y')
localcontext = ()
r = None
while r is None:
r = eval("dothat(x,y)", None, localcontext) #how do I construct
"dothat(x,y)"? with 'dothat(%s,%s)' % args?
ensure_context(args) #find/compute the formals, eg: localcontext
= (('x', 100), ('y', 200))
