No, it's entirely serious. But then I'm a fan of MSVC and especially
the team they have behind it whom are all seriously impressive
engineers at least out of the ones I've met. MSVC has lots of
outstanding features no other compiler has:

* It's vastly faster to compile, like 5x-10x faster as it's not an
AST based compiler like clang and GCC.

* It has the best debugger in the business, and still far outclasses
anything in the GCC/clang ecosystem. I still develop for Visual
Studio first because of that debugger and IDE which also debugs
Python very well indeed.

* It generates some very unique assembler which still beats the
assembler coming out of clang/LLVM, though it has fallen behind GCC
in recent years.

* It has a totally unique interpretation of the C++ standard.

* It's the last full stack compiler ecosystem left, and a major
bulwark against a clang monoculture.

My only criticism about the compiler really is it accepts too much
C++ 11/14 which won't compile on GCC nor clang, so I am still forced
to run several passes of mingw-w64 from the command line before each
git commit of new code.

If Visual Studio had a switch for the EDG red underlining tool to
switch on "don't pretend to be MSVC" in the IDE I'd be very pleased,
it would save me a lot of time.

Even better of course if Visual Studio dual compiled your code with
both MSVC and winclang and gave you a combined set of warnings.

I'd also like if Visual Studio could make use of the clang-tidy lint
tool. Since Chandler turned me onto that tool I've found it
remarkably useful for catching accidental slip ups.

But all these are minor things. VS2015 is by far the best Visual
Studio ever, and that's what matters.
