First, a simple example to give the broad strokes: foo() do: BODY
is equivalent to:
def ANON(): BODY foo(ANON)
Add del anon and the equivalence is almost exact. Call all one-off functions '_' and there is no need to ever delete the name and you have
def _(): body foo(_)
which is nearly identical to your proposed foo(&).
You can even use decorator notation to move the call before the function body: @foo def thunk(): BODY (Note that most code block ideas haven't actually made it to the PEP stage - the only one along those lines that I can see in PEP 0 is PEP 359's "make" statement, which had more to do with metaclasses than code blocks. That said, I recall assorted code block based ideas being thrown around in the PEP 340/342/343/346 discussions that eventually lead to the introduction of PEP 343's with statement and PEP 342's generator enhancements) Cheers, Nick. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia ---------------------------------------------------------------
