This is ambiguous. Is it one object with three attributes, or a tuple of three namespace objects, each with one attribute?
:a, :b, :c = x
works on any x with three attributes "a", "b", and "c". Implementationwise
I don't like the way that the colon jumps around from after the name to before the name. I don't like the way attributes are sometimes written with a dot and sometimes a colon: x = a:1, b:2 process(x.a) process(x:b) # oops. I think it is awfully mysterious syntax and beginners are going to have a terrible time working out when they should use dot and when they should use colon. -- Steven
