it's funny coming from python i missed the repl for the first few weeks but go's insane compilation speed almost completely obviates the need for one.
The few times I have tried to do serious work in python hasn't really impressed me much in that regard.
Personally, the idea of developing code that way for use in a server brings back many memories, mostly not good, so this is not a big problem for me.
that's a trick though - no one uses interpreters like that. for most people they're for experimentation, which is exactly what i was saying i'm able to do with go.
You work in your real text editor and it has a connection to a persistent session of the language runtime, over which you can send fragments, lines or whole files into. And receive data back if you wish. You can refine or replace as little or as much of the program as you want, while it is running.
Say there's a power cut and your computer turns off. No big deal because you were working in your real text editor and saving source files to disk (but not necessarily sending all of their content into the session).
It's not trivial or a novelty. I get that a traditional line-at-a-time interpreter inside a terminal à la /usr/bin/python isn't super compelling. That's not what I'm talking about.
(I am also a happy user of Go FWIW. It's the C style of programming in a super-refined form (not surprising considering who 2 of its creators are!))
...that's even closer to the style that fast compilation lends itself to
