  1. Specify impl for Show[Symbol] 

    On 2.12, `Symbol.toString` is e.g. `'foo`. On 2.13, it's `Symbol(foo)`.

I want to use `Show` to get away from the vagaries of relying on
`.toString` - to have a reliable nailed-down String representation for
types.

Want to use `Show` to build a pretty-printer, without having the output
depend on which Scala version you're using.

I tried overriding the `Show[Symbol]` instance locally, but I just got
an ambiguous implicit error. Don't know how to not import this instance,
since it's on the companion object for `Show`.
