Dear all,
I noticed setexpr help says: <op> can be &, |, ^, +, -, *, /, %
However, when one uses the hush shell additional escapes might be needed.
=> setexpr tst 3 & f syntax error => setexpr tst 3 | f syntax error
This works: => setexpr tst 3 | f => print tst tst=f
Not sure whether we should document this somewhere (or modify the help text). It took me a few minutes to realise what is going on, so a warning somewhere seems in place.
