We should use `(*regexp.Regexp).MatchString` instead of
`(*regexp.Regexp).Match([]byte(...))` when matching string to avoid
unnecessary `[]byte` conversions and reduce allocations.
func BenchmarkMatch(b *testing.B) {
for i := 0; i < b.N; i++ {
if match := versionRe.Match([]byte("v1")); !match {
b.Fail()
}
}
}
func BenchmarkMatchString(b *testing.B) {
for i := 0; i < b.N; i++ {
if match := versionRe.MatchString("v1"); !match {
b.Fail()
}
}
}
