Not that it matters, but the version of minibuf.c from "Sun 1993-05-23
03:32:05 +0000" says:

   DEFUN ("try-completion", Ftry_completion, Stry_completion, 2, 3, 0,
   [...]
   ALIST can also be a function to do the completion itself.\n\
   It receives three arguments: the values STRING, PREDICATE and nil.\n\
   Whatever it returns becomes the value of `try-completion'.\n\

You mean like lisp-complete-symbol but modal?

The functions that you can pass to try-completion and friends are
basically objcts: the 3rd argument is the method to call.  So it should
be trivial to write a wrapper that takes a CLOS object obeying
a completion-interface and returns a lambda expression suitable for
try-completion and friends.
