I’m surprised no one has mentioned Rash so I will ... perhaps Rash will be a
useful tool for you ...

Hi Mark,
How are you starting your program?
Are you launching Racket from a command line or launching by e.g.

Kieron

Hi all,
I have noticed that some recent PRs have failed the Travis CI build step
seemingly due to unrelated, perhaps infrastructure-y, problems. e.g. The PR

I'm going through The Little Schemer (Fourth Edition). On page 23 the first

Yes, specifying the language to use when interpreting some source, is best in
the input source itself than in the reference to that source.
But why must it be one or the other, and not some sensible combination of both.
e.g. If the #lang is absent from the source, look for and/or override
