What about
cmd = "Something else"
if (input("> ") as cmd):
def run_cmd():
print("Running command", cmd) # Closes over the "outer"
cmd, not the statement-local one?
Did I get that right? I don't really like it if so (I think it's
confusing) but I guess I could live with "well, don't do that then" as
an answer. And I don't have a better interpretation.
I'm still not convinced I like the proposal, but it's a lot cleaner
than previous versions, so thanks for that. Far fewer places where I
said "hmm, I don't understand the implications".
