If you're referring to the inability to deterministically reason about 
just what in the h*ll MS's API's actually do, then I agree. But the 
problem is, it's equally true of all Win APIs. Only way to fix that is 
to omit Win support entirely.

Otherwise, I disagree. I think it is not only provable, but also 
unnecessary to prove simply because such proof has never been necessary 
for Phobos, and there is nothing inherent to this problem which is 
inherently more complicated than anything already existing in Phobos 
(you can even omit the questionable modules like std.xml, it all still 
holds). Otherwise, present counterexamples demonstrating the inherent 
ambiguity/non-provability.

All phobos/compiler changes have the potential for regressions, plus we 
have unittests. Unless you can demonstrate how this necessarily goes 
above and beyond the risk from any other change in a way that cannot be 
sufficiently mitigated by tests, then the concern is irrelevant.

Provide an example where the situation is made worse.
