I don't think zsh has that directly as a variable, but it does have %_
for prompt substitution, producing on stdout a list of words identifying
the nested parser states. It's output text, not a data structure
internal to the shell (so not an array).
zsh% for i in 1; do if [[ x == x ]]; then print -P %_ ; fi; done
for then
zsh%
Of course, capturing that in $(...) will add a cmdsubst to the end.
