C# 14 extension keyword is awesome, but...
intermediate
I'm trying to make my own polyfills for some helpful things in System.Runtime.CompilerServices.RuntimeHelpers. I can add the method T[] GetSubArray<T>(T[], Range) but the compiler seems to not look at that when it is binding method calls for array slicing. Would it be really hard to allow binding to these static extension methods? That would be super cool for us living with .NET Framework. I would really rather not bring in PolySharp or other libraries into the mix. Suggestions?
