      Generally undecided; I sometimes use `implicitFooTypeclass`. Long names encourage only *deliberate* shadowing.

      that seems like overkill though... `publicImplicitValFooTypeclass`? :)

      It's a horrible way to work around accidental shadowing, but it's the best I've got.

      but how do you shadow implicits though? I thought names were irrelevant, just precedence order?

      You can shadow one implicit with another one which has the name name just by redefining the ident or importing!

      may I ask for a gist of that? I feel dense, but I thought that was just precedence and nothing to do with names

      being in the REPL, aren't you redefining foo rather than shadowing it?

      So, the "redefining" is actually an import. @travisbrown

      This maybe shows it more clearly, without any importing. https://gist.github.com/propensive/5c03fe85a3ea9558d5726efb2691cdcd … @travisbrown
