The contract would give specific guarantees heeded by all keyword
systems, as well as a reference syntax to use in SRFIs and other
specifications. Note that this is different from SRFI 177 which has a
reference _implementation_. The contract would not have one.

lol. It's apt. I find that volunteering to be the dumb person in a group
is often the fastest way to get the group to solve a problem. And at the
very least it raises the others' self esteem, which also makes the group
more productive :)
