void next_token() with switch instead of if ? about bitwise HOT 7 CLOSED

That's the opposite of readability,as it's impossible to tell without scrolling what is in ID.

If aim was readability it would either be using isalpha (and isigit for numbers) or to have macro/functions like e.g. cpython

Switch uses jump table so it's more efficient at the cost of negligible marginal size of binary output.

Amusingly, not necessary. Both gcc and icc use branches
(Also tokenizing is nowhere at the top of compiler's performance botteneck anyway)

So, @thee-engineer , you have the blessing of compilers themselves.

I would be interested to know about this as well!

Readability, perhaps?

from bitwise.

My guess: it makes character classes immediately obvious and leads a more efficient implementation (especially as the table grows).

Please reask open-ended questions like this in the forums that will be available in the next day or two. It's a good and valid question, but the issues should be reserved for specific problems. Thank you.
