Package for ordering of Go values

This package is intended to allow ordering (most) values via reflection, much like go-cmp allows comparing values for equality.

This is helpful when trying to write Less() methods for sorting structures. Provided all the types in question are supported, you can simply define it as follows:

import "github.com/ncabatoff/go-seq/seq"

type (
    MyType struct {
        a int
        b string
    }
    MyTypeSlice []MyType
)
func (m MyTypeSlice) Less(i, j int) bool { return seq.Compare(m[i], m[j]) < 0 }

Noteable unsupported types include the builtin complex type, channels, functions, and maps with non-string keys. Pointers can be ordered if their underlying types are orderable.
