@natecull @lnxw48a1 Well to be fair the compiler which wasn't fully open source was DMD, which isn't the compiler you want when you do serious development. DMD is mostly quicker to adopt new language features (since the core team works directly on it) and quicker at compilation. For serious performance LDC (LLVM based) is used and that has always been open source. Still, I think everyone is happy that the rather silly license situation around DMD has been resolved.
