Request for feedback: deriving strategies syntax

[Ryan Scott]

Bardur,

Since you don't like "bespoke", would you mind suggesting an
alternative, or advocating for a previously mentioned idea? From [1],
the ideas I've seen tossed around are:

* builtin
* standard (Elliot Cameron suggested it here [2])
* wiredin (Cater Schonwald suggested it here [3])
* magic (Andres Löh suggested it here [4])
* native
* original
* specialized (the above three are ad hoc suggestions I came up with in a hurry)
