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?
