afl's Issues

Unhygienic variant?

Hello!

I'm using afl with typed/racket and my type-expander library.

The type-expander library works by overriding define, lambda and so on. Due to afl's hygiene, #λ(…) expands to a use or lambda from racket/base, not the intended lambda from the type-expander library. Fortunately, since there are no argument or return types to expand within #λ(…), the difference does not matter, but I suppose that in other cases it could matter.

Would it make sense to also have an unhygienic version of afl directly within this package?

I needed a unhygienic version, to circumvent an incompatibility between afl and a modified version of scribble/lp2 that I use, the incompatibility is most likely on my side, but on the short term dropping hygiene seemed to do the trick, and I'll get back to my issue later. I have therefore already created the aful package, which provides #lang aful (exactly the same as afl) and #lang aful/unhygienic (unhygienic version).

If you think it's best to merge these changes in here, then I can open a PR, otherwise I can leave aful as a separate package. You can see the changes here master...jsmaniac:unhygienic if you want (this diff also includes some changes to render correctly #λ when it appears in scribble documents, using a patched version of scribble).

Regards,
Georges Dupéron

Build fails on pkg-build.racket-lang.org

Hello,

I recently wrote a small package which uses #lang afl, unfortunately it does not build on pkg-build.racket-lang.org, because afl fails to build there:

http://pkg-build.racket-lang.org/server/built/fail/afl.txt
