Thinking again, I'm not sure quite what is best. Possibilities include
having a dedicated "every" name-space:
\everyeof \l_every_eof_toks
\everypar \l_every_par_toks
\everymath \l_every_math_toks
Splitting into different modules:
\everyeof \l_ior_eof_toks
\everypar \l_<some-module>_par_toks
\everymath \l_<some-module>_math_toks
(good modules for these are not obvious)
Putting everything in the toks module:
\everyeof \l_toks_eof_toks
\everypar \l_toks_par_toks
\everymath \l_toks_math_toks
Over all, I think I prefer the first option, as these do all go
together. (If we go for _every_, do we have a very short module
"l3every" for this? If not, where do these things go?)
There is also the question of whether to provide a wrapper for
assignment to these, something like:
\cs_new:Npn { \ior_eof_set:n } #1 {
\toks_set:Nn \l_ior_eof_toks {#1}
}
or
\cs_new:Npn { \every_eof_set:n } #1 {
\toks_set:Nn \l_every_eof_toks {#1}
}
I'd probably argue that this is unnecessary. The \every... toks are all
quite low-level, and I think that it's perfectly logical if they are
given _toks names that they are then treated like any other toks.
