[ replace "==" with "=>" ]

Are you sure you didn't mean ">=" ?-)

(a) "=" vs. "==" can be confusing and buggy.
(b) ":=" for "=" breaks a lot of code.
(c) Nobody is going to change it in C or ANSI-C or C++.
(d) Lint (for those of us who have lint, *sigh*) should complain about
    "if (a=b) ..."  unless given a comment /*VALTESTED*/ or something.
(e) Compilers should compile programs that have "if (a=b) ...", and any
    complaints they generate should be turned off by /*VALTESTED*/.
