      Default values for inferred type parameters in #scala https://gist.github.com/cvogt/8672a3fd97bc97714822 … @extempore2 @retronym Does this break down anywhere?

      @extempore2 @cvogt @propensive Common misconception, I think. Parameter infer from return types is so limited most don't realize it exists.

      @djspiewak @extempore2 @propensive Is there any case where the expected return type affects type arguments that have implicits reffing them?

      @djspiewak @cvogt @extempore2 You can't get it to select between two otherwise-ambiguous implicits based on expected type, though.

      @propensive @cvogt @extempore2 I actually suspect that you can, but I don't have anything like a real use-case off the top of my head.

      @djspiewak @cvogt @extempore2 I'm just trying to construct an example, but it would be rich to call it a "real use case", working or not.
