Polyfills

[ghost]

On Github, people are developing various Polyfills to allow the use of new language features in older runtime to help people that are stuck with old .NET/.NET Framework versions. bflat, with the ability to target custom runtime, is ideal for this. Imagine that you could use C# 11 features when targeting .NET Framework 4.8 runtime only by compiling with bflat.

Would you like to join the game?

This can be a separate project same as these are for the full .net sdk. It doesn't have to live here, but I'm happy to link to it.
