environments and eval with user-defined library

[Peter Lane <peter@peterlane.info>]

I've been using eval and environment as follows:

#|kawa:1|# (define env (environment '(srfi 1)))
#|kawa:2|# (environment-bound? env 'iota)
#t
#|kawa:3|# (eval '(iota 10) env)
(0 1 2 3 4 5 6 7 8 9)

Although this works for builtin libraries (like srfi 1), this does not 
appear to work for my own libraries, e.g. below.  Notice on line two, 
the symbol is bound in the environment, so (lib test) seems to be found 
and loaded into 'env'. But during 'eval' there is no lib.test class found.

I'm running Kawa in r7rs mode, with the library in "./lib/test.sld":

$ kawa --r7rs -Dkawa.import.path="./*.sld"

Is this a limitation in the implementation?  Or do I need to give kawa 
some more information?


#|kawa:1|# (define env (environment '(lib test)))
#|kawa:2|# (environment-bound? env 'test-me)
#t
#|kawa:3|# (eval '(test-me) env)
