Based on my experiences writing an experimental Go->Haxe translator, I'll talk about the practical issues of code generation and runtime emulation required. I'll compare some of my design decisions with those of two other Go compiler/translators that build on the go.tools library. My aim is to encourage you to try one of these new 'mutant' Go compilers. I hope some of you will be inspired to contribute to one of them or even to write a new one of your own.
