Please drop the -list above.

I was hoping you'd drop all this.
See https://gcc.gnu.org/r13-1002
for implementation (both C and C++ FE) of something very similar,
the only difference there is that in the case of linear clause, it is
looking for
val
ref
uval
step ( whatever )
followed by , or )
(anod ref and uval not in C FE),
while you are looking for
memspace ( whatever )
traits ( whatever )
followed by : or by , (in case of , repeat).
But in both cases you can actually use the same parser APIs
for raw token pre-parsing to just compute if it is the modifier
syntax or not, set bool has_modifiers based on that (when you
come over probably valid syntax followed by CPP_COLON).
