My guess would be that there is no right and wrong here, it really
depends on what any given individual is familiar with. For example, I
certainly wouldn't have guessed that a GET_FIELD_DECL macro would cause
problems for autocompletion, since I personally don't use that kind of

However, what's important in a project is to pick conventions and stick
to them. For example, a lot of people initially loathe the GNU C
indentation style, but professional developers adapt themselves to
whatever style a project has chosen. There is nothing to be gained but
anarchy if personal preferences lead to churn of the "let's reindent" or
"let's rewrite in <my favourite language>" kind.

In the short term, a partial conversion to C++ gains us nothing. Even
ignoring the bugs inevitably caused by any such project, we'll end up
with a strange mish-mash of styles for a very long time, which instead
of helping anyone can only lead to confusion. I don't see anyone
committing to invest the time in converting even an entire subsystem let
alone the whole compiler. Maybe a subsystem conversion would be a good
thing to try on a branch and then present the results to the community
for evaluation. This would be better than lowering the barrier now for
all sorts of random but uncoordinated conversion efforts.
