That seems reasonable to me.
Though I did think of another encoding scheme that seems related: the
Cocoa bridge allows you to say "ns-run-loop" for "NSRunLoop". I
understand that Cocoa classes are a special case of foreign types, and
the context is a little different, but it seems like we should at
least consider whether it should be ok to write
"cf-run-loop-timer-ref" for "CFRunLoopTimerRef".
Actually, I guess there is yet another place in which users specify
foreign names, and which uses yet another scheme: The #_ and #? reader
macros, which preserve case ("#_CFRunLoopTimerCreate").
It would probably be foolish to try to settle on a single foreign type
naming scheme that could be used in all contexts and is also
convenient, but it might be OK to try to achieve a little more
How hard would it be to try to use hyphenated names like
"cf-run-loop-timer-create" in as many contexts as it made sense, with
a backup method of specifying exact case when the heuristics don't
work? Foreign classes, foreign function calls, argument types, record
types, maybe even foreign constants and variables (though these last two
would probably be most conveniently specified with the current #$
