Yes, but the rules are similar, and the operator precedence rules are
exactly the same.

I think I skipped over the "yields the token '4'" part of what you wrote
above.

`2 + 2 * 3` is a valid preprocessor expression, usable in `#if`  In that
context, the preprocessor has to evaluate it -- not to the token `8`,
but to the value 8`.

Outside a preprocessor directive, it's a valid expression (if it appears
in an expression context).  Some contexts require it to be evaluated at
compile time -- and most compilers are likely to do so regardless of the
context.  For example, given `int n = 2 + 2 * 3;` I wouldn't expect any
production quality compiler to generate add and multiply instructions.

But you were talking about something like having the preprocessor
replace the token sequence `2 + 2 * 3` with the token `8` outside any
preprocessor directives.  Yes, it would be very difficult to do that
correctly, and the only purpose would be guard against exploding macro
expansions as in the parent article of this thread.  It's probably just
not worth doing.

(BTW. I had to reboot my computer after attempting to compile the
program in the parent article of this thread.  Beware.
