Are there any plans to update the C++ version?

[panhaowen]

Now that win/macos/linux platforms have fully supported the C++17 feature, Can you support it as soon as possible?

such as:
vs2017: std:c++latest -> std::c++17
xcode4: c++1z -> c++17

emmm... 'constexpr if' and 'variant' are too convenient to use

You mean like this, this and then #1003? For Xcode, if you need it now, you can just change it locally until it's merged in premake.modules.xcode.cppLanguageStandards["C++17"] = "c++17".

Closing as this is now fixed.
