Importing Database.Esqueleto confusing in 4.0.0.0

4.0.0.0 (`esqueleto-next`/ https://github.com/bitemyapp/esqueleto/pull/325) updates Database.Esqueleto to the new syntax. I was migrating some code and struggled with confusing error messages ("Could not deduce (Database.Esqueleto.Internal.Internal.SqlSelect a0 (Entity record)) arising from a use of ‘select’") for some time before realizing I just needed to change `Database.Esqueleto` to `Database.Esqueleto.Legacy`.

I know the deprecation warning has been on Experimental forever, and possibly on Database.Esqueleto, but even so this caused me a good hour of frustration.

Is there some way to highlight the change? A migration guide or deprecation warning?

Thanks for all your excellent work!
