Thanks Matthew. That worked, but I don't fully understand why. Is having 2 reader langs before the 3rd module lang unique to s-exp here, or is it possible to chain multiple custom reader languages together like you've done?
I assumed that #lang at-exp "my-lang.rkt" should work, since I'm wanting to use at-exp syntax with "my-lang.rkt" semantics. I'll keep digging and I'm sure it will click. Finally, as a quick pointer, is there a simple way to change #lang at-exp s-exp "my-lang.rkt" into #lang my-lang? Or if I want this, do I need to implement my own reader that internally uses at-exp 's read-syntax and read functions? Thanks.
