You could improve the look a little by changing the input excepted. Say:

with delaynested( [A, B], [(A_arg1, A_arg2), B_args]):
    do_stuff()

A realistic example:

with delaynested([getlock, open], [None, ("file.txt",)]): #Notice that
the comma is important!
    do_stuff()

Is that so bad? I think it looks OK.

That said, it would be nice if there were a better way to do partial
functions than either lambda or functools.partial.
