Sure, I'm just pointing out a problem that occurs endlessly and will
continue to since the recipeprefix doesn't really address how people
get into trouble - I mean they hit trouble long before they've thought
of changing their prefix to >> or whatever. I keep coming across this
particular little problem and one lives but really doesn't learn
I think that such snags are truly because there is a bit too much
freedom. It's like this thing in C:
int i;
for (i=0; i < 10; fred(); i++);
printf("%d",i);
Oh what a tyranny it would be if for() required braces instead of
allowing you to do one-liners. Sure but it would make a class of
stupid bugs vanish.
Don't worry - I don't expect to convince anyone. :-)
Regards,
Tim
