Thanks - I'll look into syntax/module-reader.

My 2 cents is that modules like `s-exp` and `planet` as is are helpful
because they provide common service to generate the module expression for
custom language modules.  While writing the code is not a huge challenge -
having it factored out saves everyone time and effort.  I suspect many
custom languages do not include a full-module reader today.  So if `#lang
planet` is going to behave more  like `#reader` going forward, then I still
feel that we need to have a built-in `custom` module that can use a custom
reader, as Sam TH described in
http://list.cs.brown.edu/pipermail/plt-scheme/2008-July/025931.html.

Thanks,
