No.

Haskell doesn’t have implicit coercions for technical, philosophical, and almost religious reasons.

As a comment, converting between these representations isn’t free and most people don’t like the idea that you have hidden and potentially expensive computations lurking around. Additionally, with strings as lazy lists, coercing them to a Text value might not terminate.

We can convert literals to Texts automatically with OverloadedStrings by desugaring a string literal "foo" to fromString "foo" and fromString for Text just calls pack.

The question might be to ask why you’re coercing so much? Is there some why do you need to unpack Text values so often? If you constantly changing them to strings it defeats the purpose a bit.
