// concatenate arrays

concatArray_02.go

// more idiomatic concatenate slices
func concat(a, b []string) []string { 
        c := make([]string, len(a) + len(b))

concatArray_03.go

//So to concatenate two strings, using vector package I'd do?: 
        a := []string{"one", "two", "three"} 
        b := []string{"four", "five"} 
        var c vector.StringVector 
        av := vector.StringVector(a) 
        bv := vector.StringVector(b) 
        c.AppendVector(&av) 
        c.AppendVector(&bv)

Looking at concatenating strings in python and golang in a golang-nuts discussion ( http://groups.google.com/group/golang-nuts/browse_thread/thread/9d3478bec3c7c68d/dc9d1c11ac2c1a51#dc9d1c11ac2c1a51 )
