I think your initial instinct was right: if you want to change the lexical
structure of your language, the right place to start is in the reader. The
reader is the part of Racket’s language facilities that interprets the
structure of sequences of characters, and your notion of dotted identifiers
It turns out expanding the syntax object isn't the right approach. It seems
easy enough for defining values and simple procedures, but as soon as you
consider optional arguments and keyword arguments, the resulting expansion
gets too complicated to analyze.
I don't see an easy way to do this, u

I cannot help you directly, but I just wanted to say that at my workplace,
we are also behind a proxy, and I did not have to reconfigure Racket in any
way. I also have to put in the "insteadOf" rule for git clones, as only
HTTPS traffic is allowed, but I believe the Racket package manager just
Does anyone have any input on this? This is an important hurdle for my,
hopefully eventual, use of Racket at work, and I imagine it is important to
other industrial users as well.
I have confirmed that it is indeed my work's proxy/firewall that is
blocking Racket's package manager. For now, I h
Thanks Matthew, I think I can adapt that approach. As written, it's not
quite what I had in mind because it disallows foo.bar in an expression
