Someone pointed out a possible misunderstanding in the assignment expression
 debate. He said some people might think I was proposing a new operator in
 addition to '=' to act as an assignment expression so that the following
 would be true:

a = b; // Valid
a <- b; // Valid
(a = b) || 1; // Invalid, '=' is not an expression

As it turns out, what I propose is to replace '=' with '<-' or something like
 it, as well as to make it an expression.

I think many readers were aware of what I was proposing but best to explain. I
 believe I mentioned that I have already made the change. I have a working
 server running at sensemedia.net:6666 for those who wish to see what such
 a beast would feel like, or who don't believe it's possible or whatever. In
 this version the operator is '='.

Having said the above it seems we now have at four questions.

Should there be an assignment statement? (no, an assignment expression 
 is sufficient since expr; is a statement).

If there is an assignemnt statement what should it be? (=, :=, but I still
 still don't want one.)

Should there be an assignment expression? (yes, if you don't want one write

What should the assignment expression operator be? ('<-')

Thank you, drive thru.
