> Hi,
> I looked into compiling on Windows yesterday and it appears that MSVC does
> not support yet all the required C++17 features (at least, guaranteed copy
> elision and template argument deduction for class templates -- see
> https://blogs.msdn.microsoft.com/vcblog/2017/08/11/c17-
> features-and-stl-fixes-in-vs-2017-15-3/).  From some quick googling, it
> is apparently expected that full support will happen "soon" (before the end
> of 2017) so I may decide to just wait for it rather than downgrade the code
> (depending on how much time I want to spend on this...) but as a
> consequence, tinkering with mplcairo on Windows would right now require not
> only good familiarity with how to compile extension modules on Windows, but
> also with C++ to understand how to downgrade the code, so overall it may be
> quite tricky for you.
> Wx support would require refactoring the wx backend code so that the
> rendering part gets strictly decoupled from the windowing part -- this is
> e.g. the purpose of PR#8771 that does the same for Qt.  Actually, given
> that Wx already supports both "native" Wx rendering and Agg rendering, I
> expect this to be "relatively" easy, as the separation already mostly
> exists (basically we need to replace mentions of Agg by cairo in
> backend_wxagg.py).  As always, PRs would be welcome.

>>> Hi all,

>>> I would be interested in hearing your feedback.
