Updated Proposal: Revisiting Implicits

Scala Improvement Process
233

Based on the feedback I got from here I have run some limited experiments and tried some alternative syntaxes. They can be summed up as follows:

  • use witness instead of given in instance definitions: PR #7928
  • use default instead of given in instance definitions: PR #7941
  • use with instead of given for parameters: PR #7973

The experiments reflect my belief that the semantics of the new contextual abstractions are sound and work well, but that there might still be room to make the syntax clearer.

Feedback on either the PRs or here is very welcome.
