> For example, implicit conversions are now disabled by default. It's possible in Scala to pass a Foo to a function requiring a Bar due to a chain of automatic conversions from Foo -> Baz -> BazMutable -> Bar. This is fun and magical but difficult to understand and debug. The community and language itself now suggests against this pattern.

Oh God I'm having flashbacks to using Lift in... 2012? There were about four levels of implicit conversions between my model and the final JSON, trying to understand that was hard.

That said, David Pollak the founder of Liftweb was amazingly helpful on on their mailing list.
