…1520) ## Changes This PR makes two changes: 1. In #1510 we'll be adding multiple associated location metadata with a dyn.Value. The Go compiler does not allow comparing structs if they contain slice values (presumably due to multiple possible definitions for equality). In anticipation for adding a `[]dyn.Location` type field to `dyn.Value` this PR removes all direct comparisons of `dyn.Value` and instead relies on the kind. 2. Retain location metadata for values in convert.FromTyped. The change diff is exactly the same as #1523. It's been combined with this PR because they both depend on each other to prevent test failures (forming a test failure deadlock). Go patch used: ``` @@ var x expression @@ -x == dyn.InvalidValue +x.Kind() == dyn.KindInvalid @@ var x expression @@ -x != dyn.InvalidValue +x.Kind() != dyn.KindInvalid @@ var x expression @@ -x == dyn.NilValue +x.Kind() == dyn.KindNil @@ var x expression @@ -x != dyn.NilValue +x.Kind() != dyn.KindNil ``` ## Tests Unit tests and integration tests pass.

Changes
There are four different treatments location metadata can receive in the
convert.FromTypedmethod.This PR ensures that location metadata is not lost in any case; that is, it's always preserved.
For (2), this serves as a bug fix so that location information is not lost on conversion to and from typed for nil values of complex types (struct, slices, and maps).
For (4) this is a change in semantics. For primitive values modified in a
typedmutator, any references to.Location()for computed primitive fields will now return associated YAML location metadata (if any) instead of an empty location.While arguable, these semantics are OK since:
