I'm going off on a tangent (again, as usual:-), but would it be an idea
to add a "meta-reserved-word" to Python, so it would become easier to
add new constructions to the language?
What I envision is something (let's call it "keyword" for now, even
though that's probably a bad choice) that we could use to make an
identifier a keyword. So, if we're discussing a
lock .....:
<block>
statement at some point this would be implemented in 2.N as
keyword(lock) ....:
<block>
with lock not a reserved word (but it would generate future warnings).
In 2.N+1 lock would become a reserved word. But: keyword(lock) would
also continue to work for all eternity. (And, as a corollary, you could
use keyword(class) and any other construct too).
I don't have intimate knowledge of the workings of the parser, but I
can't imagine that this would be difficult on that account.
