} That's obviously a bug.  The fix is easy, although I don't know why the
} case of end of input in a normal input sequence, just above, needs to be
} different.

This solves the specific example but doesn't solve the general problem;
if there is a parse error inside $(...) then ${(z)...} fails.

torch% a='x $() y'
torch% print -rl -- ${(z)a}
x
$()
y
torch% a='x $(|||) y'
torch% print -rl -- ${(z)a}
x
$(||
torch%
