Consider the following program

package main

import (
    "fmt"
)

type X struct {}

type Y int

type Z map[Y]*X

func test(z Z) {
    for _, k := range deriveSorted(deriveKeys(z)) {
        fmt.Println(z[k])
    }
}

func main() {
    z := map[Y]*X{}
    test(z)
    fmt.Println("Succes")
}

Running goderive runs fine, but subsequently the program fails to compil

Find will return the index of the first element that matches, or -1 if none match.

Parent issue: #335
Every plugin must be able to use all properties to construct the exact PSI element being fed in to achieve isomorphism between Quote and Scope. To ensure that AST parsing and our quote-and-template system is robust, more testing is needed to increase stability and reliability.
