Hello! See snippet: --- interface AST { static interface Expr : AST { final static class Name : Expr { override void accept(AST.Visitor v) { v.visitName(this); } } } final static class Visitor { void visitName(AST.Expr.Name

Why is the fPIC switch missing?

Hello. My problem is exactly what it says on the title: my dmd (windows 7, x64) doesn't seem to have -fPIC: --- dmd -fPIC Error: unrecognized switch '-fPIC' run `dmd` to print the compiler manual run `dmd -man` to open browser on manual --- `dmd --help` also doesn't have

Forgot to say: dmd v2.088.0. Also, weirdly enough, `dmd --version` outputs `DMD32 D Compiler v2.088.0-dirty`. Why is "dirty" there?

What's the difference between DIP25 and DIP1000?

Hi, I've been reading about DIP25 and DIP1000 and I'm not quite sure if I understand the difference between the two—is DIP1000 supposed to be a rework of DIP25? And what's the difference between `return ref` and `return scope`? Also, will there be any compiler version where `-preview=dip25`
