If you have your hands on an evar in Ltac, is there a way to get it as a
goal? For example, could I do something like:

match type of H with
| _ /\ ?R => is_evar R; R: refine (_ : _ /\ _)
end

That doesn't work for me at all - why not ...=> is_evar R; assert R?

Also, this doesn't answer my question of how to deal with evars buried deep inside of complex terms.
