Given a string - execute a function by the same name

Erik,

> Perhaps I missed something earlier in the thread, but I really don't see the need for that registry dict or the register decorator. Python already
maintains a dictionary for each scope:

The advantage of the decorator technique is that you explicitly declare
which functions are eligible for execution.

Using locals() is too broad because it might allow a user to execute an
unintended function.
