If the lexer can't find the closing '))' on the command line, it tries
to interpret the opening '((' as '( (', i.e., nested subshells.

zsh% ((echo foo) )
foo
zsh% ((echo foo); echo bar)
foo
bar
zsh% ((echo foo)
subsh>

${(z)...} uses the same lexter, and even if it is OK to make it behave
differently from the command line, we may need to modify the lexer ...
