Finally, there is another axis of crystallization, the axis between
different Scheme implementations. Guile does not yet support the latest
Scheme standard, R7RS, and should do so. Like all standards, R7RS is
imperfect, but supporting it will allow more code to run on Guile
without modification, and will allow Guile hackers to produce code
compatible with other schemes. Help in this regard would be much
appreciated.
