If we are left with several alternatives after normal overloadiong resolution and the expected result type is not a FunProto, prefer the alternatives that do not have a method result type. This makes i2378 compile, so it got moved to a pos test.
The error that was checked for in the test is no more.
The previous code did not compose correctly with the "no defaults" criterion that followed.

There was a problem hiding this comment.
As pointed out by @michelou , we can just use noCurriedCount instead of noCurried.length .
