} While this sort of thing and the problems with modular conditions are a
} real headache for parsing, I don't think the actual practical problems
} are anything like as bad.
It's almost certainly not a problem for correct programs. The case I'd
be worried about is a program that ksh would reject as syntactically bad
(and therefore never start running) where zsh would accept it and then
fail at run time (possibly creating side-effects).
However, having had this situation already for a rather long time, I am
not particularly worked up about it.
