X11 toolkits have been appearing in Scheme lately and and I have
started to worry about compatibility.  So far I've seen bindings for
X11 in cscheme 7.0, elk and c-to-scheme and I'm suspect there are
several more.  I think that its very important to quickly settle on a
set of standard low-level bindings, otherwise it will soon be
impossible to port user interface code from one Scheme environment to
another.

The c-to-scheme system from DEC Western Research Laboratory provides
something particularly nice: a software tool, cdecl, which will parse
the header files of C libraries and builds the Scheme structures
necessary to link Scheme programs to that library.  The mapping
between procedure names and between C and Scheme data structures is
standardized by this tool.  It would be of great benefit to the Scheme
community to port this tool as this will give Scheme programs access
to the world of libraries and system interfaces available to C
including X11.

I'm interested to hear what people have to say about this issue,
especially people in charge of Scheme implementations.  I think that
this is an urgent issue.
