Overloaded .map inference problem #6

Closed KadekM closed 7 years ago

KadekM commented 7 years ago

Currently inference fails on this (scala 2.11):

 observable.map {
      case ...=> ...
      case..  => ...
    }

missing parameter type for expanded function
[error] The argument types of an anonymous function must be fully known. (SLS 8.5)
[error] Expected type was: ?
[error]     observable.map {

Could we prehaps rename

  def map[R](project: (T, Int) => R): Observable[R] = {

to something else ? Like mapWithIndex

That would fix the inference problem.
