>Go compiles so fast you can just pretend there is dynamic eval.

Yes, the Go people keep mentioning that. You might as well eat soy and pretend it's a delicious steak.

For people that have used good REPLs, from Lisp machines to iPython, it's not the same thing at all.

You lose your state, you loose context, you loose good introspection, etc etc. And if you try loading stuff that's big (several packages as dependencies etc), the compile time starts adding up too.
