[C++ Draft] PR 54080 / PR 52875, others


Hi,

for reference I decided to start a new thread with a preliminary implementation of this idea:

    http://gcc.gnu.org/ml/gcc-patches/2013-08/msg00519.html

I know Gaby doesn't like it much, would like to see something more ambitious in this area.

IMHO, within its limits, the idea works as I expected it would, both the mentioned bugs are fixed and we produce a sensible diagnostic. No regressions, testsuite changes, nothing changes in terms of rejecting testcases which exceed in SFINAE context the recursive instantiation / substitution limit.

I'm thus attaching the draft below, let me known if you can imagine ways to incrementally improve it in the near future.

Thanks!
Paolo.
