// Package trim removes some redundant values from CUE sources.
//
// The most common use of trim is to remove duplicate values from data
// where a definition now provides the same value. For example:
//
// servers: [
// {role: "web", cpus: 1},
// {role: "db", cpus: 1},
// {role: "proxy", cpus: 1},
// ]
//
// #server: {
// role: string
// cpus: 1
// }
//
// servers: [...#server]
//
// Trim will simplify this to:
//
// servers: [
// {role: "web"},
// {role: "db"},
// {role: "proxy"},
// ]
//
// #server: {
// role: string
// cpus: 1
// }
//
// servers: [...#server]
//
// This works with defaults too. Given:
//
// servers: [
// {role: "web", cpus: 1},
// {role: "db", cpus: 4},
// {role: "proxy", cpus: 1},
// ]
//
// #server: {
// role: string
// cpus: *1 | int
// }
//
// servers: [...#server]
//
// Trim will simplify this to:
//
// servers: [
// {role: "web"},
// {role: "db", cpus: 4},
// {role: "proxy"},
// ]
//
// #server: {
// role: string
// cpus: *1 | int
// }
//
// servers: [...#server]
