+    return
+  }
+
+  m := r.match_str('Match everything after this: "I <3 VLang!"', 0, 0) or {
+    println('No match!')
+    return
+  }
+
+  // m.get(0) -> Match everything after this: "I <3 VLang!"
+  // m.get(1) -> "I <3 VLang!"'
+  // m.get(2) -> Error!
+  whole_match := m.get(0) or {
+    println('We matched nothing...')
+    return
+  }
+
+  matched_str := m.get(1) or {
+    println('We matched nothing...')
+    return
