I just ported Cur to use this version of Redex
(https://github.com/wilbowma/cur/tree/redex-with-binding), and was able
to delete and simplify many lines of code and get all tests passing in
minutes. Hurrah! Although, I do not have interesting binding structure.

Another approach is to use something like cordova. It basically wraps an
html/js app in a container that runs on the phone as an app. It's cross
platform and exposes phone functionality through plugins. You could always
write a racket webapi server if you needed server side processing.

It's pretty real world for me.

I've figured out where the error is coming from, but I still have no idea
what's going on.

I would personally caution against it, for the following reasons:
1. At least for Android, most of what you will need for this is interfacing
with the respective gui libraries, which take a bit of getting used to, even
just using Google's relatively helpful and complete documentation. Working wit

I am about to start writing an app. Really all it will have to do (for now)

I just rewrote an existing C++ server in Racket in two days, dropping 2,000 C++
lines to 700 Racket lines.
The architecture of the previous server was based on fine planning and
implementation, but quickly degraded from an 18-month succession of band-aids.
Having laid out a replacement plan, I
Okay, I am here again.
No lucky, I cannot make it cooperate with the precision GC, even catching
the signal does not work.
The `xform` seems buggy in two ways I have encountered:

`syslog` macros 'facilities', 'severities' and 'op
