This reflects changes from a number of approved proposals:
- #920 : concrete statements about orphan and overlap in Carbon
- #2138 : "generic" -> "checked generic", "template" -> "template
generic"
- #2188 : binding patterns are forbidden in type position
- #2360 : "type", "facet type", "facet". Note: I am not using the term
"generic type" from #2360 since that meaning conflicts with the
generally accepted meaning of "generic type" of a type with a
compile-time parameter.
- #2760 / #2770 : internal/external impl -> extending impl
- #2964 : "symbolic constant" and "template constant"

This proposal has three main contributions:
- Types with generic parameters have an identity that consists of the types names plus the values of those parameters.
- The parameters of a type may be deduced from a function's argument.
- Types with generic parameters do not support specialization. Instead, a type can delegate to an interface to opt in to allowing specific customization points.
