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"

e48df78938 feat(frontends/lean/elaborator): do not apply delayed_coercions on equation lhs 
The variables in the equation lhs do not have type at preprocessing
time (i.e., their type is a metavariable). So, they may seem candidates
for delayed_coercions. If the coercions are injected, we will not be
able to pattern match. Thus, we disable coercions in this case.
