that this would make teaching R easier.
Just one last comment to finish off my participation in this thread. I
think that in general, "+1" votes mean almost nothing. To have a change
accepted, you need to convince a member of R Core that it's a good idea,
without convincing another one that it's a bad idea.
Personally I listen to arguments for changes, but repetitions of the
same argument are just irritating. I was not convinced by the
copy-and-paste argument. I think that if this is causing you problems
in teaching, you're doing it wrong. I'm not going to be convinced by
repetitions of that same argument.

Btw, thank you Paul for the link to your coding style document. It was
a nice read.
Cheers

+1 to having runnable code emitted
It does emit runnable code, which is why Herve's complaint was
nonsense. It doesn't emit code of which every substring is runnable.

patch seems to work nicely, hopefully R-core will agree to
apply it to HEAD
