So this complexity highlights to me one important thing: whatever group of
MSVC tools are
selected as the baseline, it would be really helpful to have people
about that contribute to the description of precisely which C++11
constructs are
allowed (and if there are any surprising cases which don't work), for those
of us
who have no idea precisely what will get past an MSVC compiler and no means
or desire to set up a Windows system just for testing. It's very
frustrating when
development turns in to a "I checked on all my systems, checked in and get
complaints from people on very different systems whose build broke"
(Yeah, I know there's any irony there...) Getting a clearly delimited
feature list
should help reduce that.
