Please try to learn how to write a good proposal. A few examples, like you did here, just isn't enough. It's worth doing right, and it's worth *learning* how to do it right.

It seems I have to repost the proposal I already wrote...

My proposal is to add a way for third party modules to add custom
keywords. Example:

from mykeywords import @const
@const a = 1

Notice that I choose "@" but I hope another non c-alphanumeric
character will be chosen.

No syntactic changes are needed. Custom keywords *must* be prefixed
with a non-alphanumeric character (@ for example).
