let’s perpetuate the helplessness because developers will not understand. That might be the rationale that also prevailed to make swift have no namespaces: Objective-c did not… funny thing is, the compiler source code would be miserable to read if its source code was organized in terms of classes and modules (lib). Which means that aside from accessibility to LLVM API, attempting to write a Swift compiler in Swift today would probably result in hard to read/reason about source code.
