Matthew and I talked about this today, and we decided that we should
create a parallel set of matchized versions of the `for' macros,
rather than my previous experiment which added an `in-match' form that
changed the semantics of `for' clause bindings. I've started
implementing this; fortunately

Probably the right way to do this is for me to add a
`prop:match-expander' which can be added to arbitrary structure, and
then to use that in lang/private/firstorder on the `fo' struct.

On StackOverflow [1], someone reported that Racket's I/O performance
on large files was substantially worse than other languages for a

data, but I did see a performance difference relative to Chicken for
large but not huge files,
This just started happening to me as well.
