Sample file that will generate gorename errors

example.go

package main

// Running gorename -from example.go::Foo -to foo on this file will not work.
// There are multiple errors, but it appears that gorename stops after the first one.
//
// example.go:16:6: renaming this type "Foo" to "foo"
// example.go:21:6:        conflicts with func in same block
//
// After commenting out or changing foo(), the errors moves down:
//
// example.go:16:6: renaming this type "Foo" to "foo"
// example.go:24:12:       would cause this reference to become shadowed
// example.go:24:8:        by this intervening var definition
//
// Fixing that function and things move to the same error in b()...
type Foo int

func main() {
}

func foo() {
}

func a(foo Foo) {
}

func b(foo Foo) {
}
