Might be that it doesn't do keyword objects, string->keyword? 2014-12-07 13:10 GMT+02:00 Chris Vine <chris@cvine.freeserve.co.uk>:

The following works fine without the syntax-rules/syntax-case macro expander enabled:

(open-vector-pipe (list direction: 'input) (list direction: 'output))

However if the syntax-case expander is enabled, compilation generates a warning that 'direction:' is undefined and runtime fails with:

*** ERROR -- (Argument 1) VECTOR or port settings expected (open-vector-pipe '(#!unbound input) '(#!unbound output))

This also works without the syntax-case expander:

(open-vector-pipe (list 'direction: 'input) (list 'direction: 'output))

but fails with the syntax-case expander enabled with a different error:

*** ERROR -- (Argument 1) VECTOR or port settings expected (open-vector-pipe '(|direction:| input) '(|direction:| output))

I am using gambit-c 4.7.3. Is there any workaround for this?
