catch not an rvalue
Tue Feb 19 17:21:57 CET 2002
Hope this isn't another RTFM, but I can't resist asking.
Am going through the puzzle box while home with the flu.
During prototyping, it would be nice to replace
X = <risky expression>
X = catch <risky expression>
but the shell (and compiler) don't like that.
Just wondering why the syntax error is happening.
Didn't see the answer in, e.g., Chap 6 of
2> X=catch 22.
** 1: syntax error before: 'catch' **
3> F=fun()->catch 22 end.
