Any other thoughts about how to get the failure info? This is
probably the main complaint against __traits(compiles), that there's
no way to find out what went wrong if the code doesn't compile. Often
it can just be a typo. I know I've spent plenty of time looking at
static if(__traits(compiles, ...)) checks that weren't working only to
discover I switched an x for a y somewhere. Or passed the wrong
number of arguments.
I agree it's a problem. Perhaps we can do:
__traits(compiles_or_msg, ...)
which would print the error messages, at least making it easier to track
down.
