Sometimes I have cases when
\everypar calls in other group level than before. For example,
\everypar calls inside document, but the second time it calls inside
Is there an existing variable in
expl3 which allows us to know the group level to compare it inside
\everypar command? If not, how to solve it for all environments?
Maybe I should redefine
\egroup commands, and increase or decrease my own variable connected with the group level? If yes, how it do correct?
