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`.

This should be solvable, can you create a small example that demonstrates the problem? |
