### Flask REST frameworks

There are several Flask REST frameworks, but after investing the time and work into investigating them, I found that many are discontinued or abandoned, with several standing issues that made them unfit.

You pay 💸.

The cashier goes to the kitchen.

You wait, standing in front of the counter 🕙, so that no one else takes your burgers before you do, as there are no numbers for turns.

implies observing the write to <code>a</code>.  This
version can (incorrectly) print an empty string
instead of <code>"hello, world"</code>.

<p>
Another incorrect idiom is busy waiting for a value, as in:
</p>

<pre>
var a string
var done bool

func setup() {
	a = "hello, world"
	done = true
}

func main() {
	go setup()
	for !done {

    return new Builder<>(expectedSize);
  }

  static void checkNoConflict(
      boolean safe, String conflictDescription, Object entry1, Object entry2) {
    if (!safe) {
      throw conflictException(conflictDescription, entry1, entry2);
    }
  }

  static IllegalArgumentException conflictException(
      String conflictDescription, Object entry1, Object entry2) {
    return new IllegalArgumentException(

            }
        }
    }

    static String queryLookup( String query, String param ) {
        char in[] = query.toCharArray();
        int i, ch, st, eq;

        st = eq = 0;
        for( i = 0; i < in.length; i++) {
            ch = in[i];
            if( ch == '&' ) {
                if( eq > st ) {
                    String p = new String( in, st, eq - st );

    val call = client.newCall(request)
    val response1 = call.execute()
    val cloned = call.clone()
    val response2 = cloned.execute()
    assertThat("abc").isEqualTo(response1.body.string())
    assertThat("def").isEqualTo(response2.body.string())
  }

  @Test
  fun legalToExecuteTwiceCloning_Async() {
    server.enqueue(MockResponse(body = "abc"))
    server.enqueue(MockResponse(body = "def"))
