The errors are delayed in exactly the way that they are for the contract
'(- none/c any/c)'. If you apply that contract to 'add1', it doesn't error
unless the resulting function is applied.

Yeah -- that would make distribution much easier, since it will be

The cond issue also shows up in TR. We should and will have to tackle it.
In TR, this is less of an issue, because you get a type error when you
unexpectedly fall off the end of a `cond`. So I think this is in some

The only bit that bothers me is the (begin (not (flonum-wrapper? x)) ...)
stuff left lying around after TR's optimizer eliminates the branches in the
expansions of `fw+'. IIRC, they cause futures to sync, but I'm going
analysis, then that would be nice, but it would be harder,
since it would require recording information for the output of
`make-struct-type`. Typed Racket has information about structures at a
higher level.

Thanks for figuring this out!
It looks like Patch 3 or readline 6.2 fixes this bug:

but I don't know how to detect that, or whether any systems are
