Make that "like an if 0:"
Of course an ordinary embedded def is really not "skipped over" -- it is executable
code that binds the function name to stuff pulled together to make a function.

I was thinking of the new local def I am proposing, which in contrast does not
bind separately compiled code, but defines local compiled code that is
as much part of the current code as an if statement suite in the same position
would be. In fact, identical except for a new local return byte code at the end,
given that the def parameter declaration guarantees that local bindings for them
exist for the suite. Thought I'd better clear that up ;-)
