If a pre-allocated slice is declared by var statement and explicit type, it would be incorrectly reported as a candidate for pre-allocation.

For instance, the code snippet following would be reported.

package main

func main() {
	var s []int = make([]int, 0, 100)
	for i := range "Hello" {
		s = append(s, i)
	}
}

// Output:
// .\testdata\sample.go:4 Consider preallocating s
