rnrs hashtables

[Jamison Hope <jrh at theptrgroup dot com>]

I just tried to do this:

> (import (rnrs hashtables))
> (define objects :: hashtable (make-eq-hashtable))

and got the error "unknown type name 'hashtable'". So I looked, and,  
sure enough, 'hashtable' isn't exported. This works:

> (import (rnrs hashtables)
>         (only (kawa hashtable) hashtable))
> (define objects :: hashtable (make-eq-hashtable))

but seems a little tedious. I know that kawa/lib/rnrs/hashtables.scm  
is exporting exactly the set of functions called for in the R6RS  
chapter on Hashtables, and so I'm not sure whether to classify this as  
a bug or just an inconvenience.

There's obviously contention between pure (untyped) RNRS Scheme and  
native (typed) Kawa; Per, is it your intention when implementing rnrs  
standard libraries to export only the functions in the spec and not  
the underlying data types which they use? That should be in the  
documentation, I think.
