What is the best Scheme implementation for working through SICP?

Question

I have been using PLT Scheme, but it has some issues. Does anyone know of a better implementation for working through SICP?

Answer 1

I'm now working through SICP using Chez Scheme. It's a pretty old dialect of Scheme, so presumably it isn't too far from what SICP was written around.

Note that the Chez Scheme project page links a Windows binary and source that can be built on Unix-like platforms. But if you're on a Mac, you'll probably want to do

brew chezscheme
man chez

Assuming you have homebrew, which you really should.

Why not MIT Scheme? Because the interactive front end is Edwin, an editor that uses EMACS conventions. (Currently, it's an actual EMACS mode, tho it used to be implemented in Scheme.) I used to know basic EMACS, but my skills atrophied from disuse, which tells me that relearning this editor is just not worth the trouble.

Why not DrRacket? If I had seen @frederick-squid 's brew instructions, I might have given it a try. Instead I tried to follow the official instructions for scheme and sicp, which are seriously out of date. Then I tried to make the IDE go into scheme mode, which seems to be intuitive but isn't.

Just too much trouble. And I'm not sure I want to get into a fancy language design IDE, especially one whose poor support of Scheme sparked the original question.
