8b7dc4e03a feat(frontends/lean): apply eta-reduction in postprocessing step 
Perhaps, we should add an option to disable this new feature.

Remark: this commit makes commit 46d418a redundant.
I'm keeping 46d418a because we may retract this commit in the future.

add test/example that defines count_vars using tactics and recursors.

allows us to use recursive equations.
The recursive equations are compiled into recursors.
