Earlier this evening I tried to run the Go [modernize](https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize) analyzer on OPA. That didn't go as planned: - https://github.com/golang/go/issues/73661 - https://github.com/golang/go/issues/73663 While we wait for that to be fixed, I figured an old-fashioned search-and-replace across the repo may work for at least the `interface{}` to `any` conversion. That should help make it easier to see the other fixes as applied by the modernize tool once it has had those issues resolved. Signed-off-by: Anders Eknert <anders@styra.com>

// Compare returns an integer indicating whether two AST values are less than,

// Different types are never equal to each other. For comparison purposes, types

|
|
// and all corresponding elements are equal. If one element is not equal, the

|
// return value is the same as for the first differing element. If all elements
|
|
// are equal but a and b have different lengths, the shorter is considered less
|
|
// than the other.

//
|

// Objects are considered equal if and only if both a and b have the same sorted
|
|
// (key, value) pairs and are of the same length. Other comparisons are
|
|
// consistent but not defined.
|

//
|
|
// Sets are considered equal if and only if the symmetric difference of a and b
|
|
// is empty.
