If you can do that, why not return the literal representation of the type
hinted function?
For the repl you could provide a function that interns the type-hinted
function into the namespace by evaluating the literal representation first.

certain types have been provided to your namespace correctly at the repl,
run 'lein type <namespace>' to type hint everything in the namespace by
literally restructuring the file.
Things type hinted with expressions would be tricky, but this could work
(or you could just leave it alone):
myfn (original)
myfn-int
myfn-long
myfn-float
etc....
