Both GCC and LLVM back-ends support computed gotos (despite the asm produced by LLVM on them is not as good as GCC one). If people feel the desire to add compiler-specific computed gotos to D, they will risk adding them with a different syntax on each present and future compiler.
What did you had in mind?
The following would only require a minor syntax change. auto codeaddr = &Label; goto codeaddr + 0x10; GotoStatement: goto Identifier ; goto Expression ; // NEW goto default ; goto case ; goto case Expression ;
