+/**
+This is a tricky issue which has to do with the fact that too much conflicting
+type information is propagated into a single implicit search, where the intended
+solution applies two implicit searches.
+
+Roughly, in x + x * y, the first x is first typed as Poly[A]. That
+means the x * y is then typed as Poly[A]. Then the second x is typed
+as Poly[A], then y is typed as Poly[Poly[A]]. The application x * y
+fails, so the coef2poly implicit conversion is applied to x. That
+means we look for an implicit conversion from type Poly[A] to type
+?{val *(x$1: ?>: Poly[Poly[A]] <: Any): Poly[A]}. Note that the result
+type Poly[A] is propagated into the implicit search. Poly[A] comes as
+expected type from x+, because the lhs x is still typed as a Poly[A].
+This means that the argument of the implicit conversion is typechecked
+with expected type A with Poly[A]. And no solution is found.
+
+To solve this, I added a fallback scheme similar to implicit arguments:
+When an implicit view that adds a method matching given arguments and result
+type fails, try again without the result type.

+// This one is weird and nasty. Not sure if this is scalac or sbt

+// Exts seems to need to be defined in separate file.

+// Steps to reproduce:
+// 1. sbt clean
+// 2. sbt run (it works)
+// 3. Comment A & uncomment B.
+// 4. sbt run (it fails)
+// 5. Switch it back & sbt run. It still fails.
+//
+// In this project sbt clean helps. However in a large project where this
+// bug was found compiler crashed even after doing sbt clean. The only
+// way to work around this was to reference Exts object explicitly (C) in
+// the source file using its implicit classes.

+// Lets suppose this is a mega-trait combining all sorts of helper

+// The type #4 from the old version is problematic: the parameter is typed with
+// a skolem for the type parameter `A`. It won't be considered to match the
+// method it overrides, instead they are seen as being overloaded, and type inference
+// goes awry (Nothing is inferred as the type argument for the recursive call
+// to coflatMap.
+//
+// The Namers patch adds one step here: it subsitutes the type parameter symbols
+// for the skolems:
+//
+//  https://github.com/scala/scala/commit/b74c33eb#L2R1014
+//
+// So we end up with a method symbol info:
