I'm not sure that's universal. Using Standard ML at Uni, it was often
useful to use "let name = expr in expr" (or whatever the syntax was)
to simplify an expression. Directly borrowed from mathematics, I
'name' is not a variable, of course; there are no variables in
functional programming. Can't remember what it's called -- named
I think I use local names in Python about as much as I did in SML.
