a=(b=1,b)+(b=2,b)+(b=3,b); /*ANSI does NOT say a=6*/

[Wayne Throop]

Awright, awright, I forgot to parenthesize the assignments to b.

I will also take this opportunity to point out that ANSI *might* be
taken to imply a must get 6, if the meaning of their wording
restricting interleaving of expressions isn't what I think it is.

without using the letter 's'.
