OK, you've lost me here :) All I was suggesting was substituting | for # :
if # can cover something, then I guess | can as well. It's mostly
Whether | or # should cover identifiers or arbitrary code fragments is
another discussion (I had assumed that | would cover identifiers and we'd
have another mechanism for code fragments: my mistake). In my opinion we
will have to come up with a mechanism for precise specification of remote
identifiers. In English: if a doc string references "a" and a is within the
namespace of the current module/class/method (via imports or other
definitions etc) then I'm happy (my system contains all the information
necessary for this to work as one would expect); if it isn't then I think
I'd need a way of specifying exactly what "a" is referring to so as to avoid

I don't think you need to worry about this: we all seem to agree that ' ' is
crufty for code markup.
Not that we've agreed on an alternative yet <wink>.

What I would like is something that can be *mostly* understood in a short
space of time (10 seconds is pushing it), but which explains all those nasty
little what-ifs in a more precise way somewhere else.

OK, I think I agree with that. Nested font changes are probably evil, but
they weren't my original thinking (I thought | might do for identifiers and
<Code> for code fragments etc. That seemed, by default, to allow nested font

I want to keep doc strings as simple as feasible, but I've also never bought
into the whole vspace argument (witness someone's complaint about the
whitespace I use), probably because the world I've been bought up in has big
screens and no line editors <wink>. I guess I'm trying to strike a
compromise between ultimate simplicity, and C++ doc TeX monstrosities
neither of which seems quite appropriate.
