Hi,

Which wouldn't be so weird: in the libstdc++-v3 code we do it all the time.
Yea.  I actually reviewed the libstdc++ guidelines to see where they differed
from GNU's C guidelines.

I'm strongly in favor of dropping the horizontal whitespace between the
method name and its open paren when the result is then dereferenced.
ie foo.last()->e rather than foo.last ()->e.
I'd prefer to not write in this style at all, like Jakub.  If we must
absolutely have it, then I agree that the space before _empty_ parentheses
are ugly if followed by references.  I.e. I'd like to see spaces before
parens as is customary, except in one case: empty parens in the middle of
expressions (which don't happen very often right now in GCC, and hence
wouldn't introduce a coding style confusion):

do.this ();
give.that()->flag;
get.list (one)->clear ();

I'd prefer to not have further references to return values be applied,
though (as in, the parentheses should be the end of statement), which
would avoid the topic (at the expensive of having to invent names for
those temporaries, or to write trivial wrapper methods contracting several
method calls).
Seconded, even give.that()->flag; is ugly.

I don't find it ugly :-)

so my example would end up being
   int unsignedsrcp = ptrvar.type().type().type_unsigned ();  ?
I can live with this suggestion... its the sequence of 2 or 3 or 4 empty parens with spaces that I really found distasteful.
