You may wish to read up on scsh. While it was way ahead of its

would be quickly useful to people used to basic shell scripting
syntax. After all, this syntax has a 40+ history and shouldn’t be
thrown out.
What Matthias said...
I think that Olin Shivers made a lot of excellent syntactical decisions
when designing scsh -- in particular his syntax for regular expressions
and for extended process forms -- to the extent that if one were simply
to reimplement the scsh syntax in Racket, that would be an excellent
departure point. This is not to dispute your own syntactical choices,
but in an enterprise like this, scsh would be the elephant in the room.
There have been a couple of attempts to support the scsh syntax in
Racket, and the scsh code is still under active, though rather
low-level, maintenance <https://github.com/scheme/scsh>. Incidentally,
scsh does start up very quickly, which is an attractive feature.
And this enthusiasm isn't just because scsh was the first Scheme
implementation I spent serious time with (*wipes wistful tear*).
Best wishes,
Norman
