002050fa97 feat(frontends/lean): increase binding power of ! and @ 
Remark: I did not add the constant "app".
Reason: It would break the standard library in many places.
Moreover, the current "max" is not just the binding power of
application, but also the binding power of identifiers, (, [, ...
It would be weird to call it "app"
