It is not syntactic sugar, "x := 10" is an assignment expression in contrast with "x = 10", which is a statement.

Hence the former can be used in contexts like "if x := 10: pass", which is the whole point of the PEP.

Why is it not syntactic sugar? It looks like convenience. You could argue everything above machine language is syntactic sugar.

Type inference is not.
