Hey Douglas,

Perhaps I was being too abstract? Here goes:

,-------------------------------
| def selector():
| ...
| return funcKey #get down get down
|
| def func():
| ...
| funcSwitch = {}
| funcSwitch[funcKey] = func
| ...
| funcSwitch[selector()]()


Thanks Warren, I was merely pointing out the typing mistake you made in your first example.

And yes, your abstract names made it difficult to guess the intention of the original code. With the meaningful names you've just provided, I can see immediately that you intended to write the 2nd working code alternative I suggested:

Oh no, I get it, you meant...
,----
| c['b'] = b
| c[a()]() #works!
`----
