Yes.  Some of the detail is wrong (for example a compiler can sometimes
remove a recursive function call altogether, and inling is often clever
than you think) but the main problem is that you are thinking about it
at all.

Your best bet, by far, is to prototype your parser and do some timings.
You can then throw it all away if you need to but you'll have some real
data to work with.  you may find that other choices (32-bit characters
for example) are far more costly than a function call now and then.

The joy of a recursive solution is you should be able to knock one up in
a day or so and you can start working from data rather than guesses.
