The best way to pass the Dave Test is to ask him directly, for example:
Do you think the stdlib team would be okay with a naming scheme like
Syntax.Literal.ArrayProtocol, Syntax.Literal.IntegerProtocol, etc. We think
this produces a clear description of the conformant role and one that is unlikely to be
misinterpreted. It may read less fluently but it's also less subject to confusing users.
This naming scheme uses the Syntax namespacing, and creates a Literal subspace.
Each protocol is named as "XXXXProtocol". This introduction a distinction between
"This is/can be used as an integer literal" and "Conforming to this protocol ensures
that an instance of the type can be written as an integer literal".
The problem with earlier approximations was that people saw "Syntax.IntegerLiteralXXX"
and thought the typed could be substituted into expressions where an integer literal
was used, and not that an integer literal could be be used to write an instance of
So what do (and your team) think of this idea?
