Compiling never end with some code examples

[MaxGraey]

Minimal example:

const HEX_CHARS: string[] = [
  '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
  'a', 'b', 'c', 'd', 'e', 'f'
];

export class Sha1 {
  hex(): string {
    let 
      h0 = 0,
      h1 = 1,
      h2 = 2;

    return (
      HEX_CHARS[(h0 >> 28) & 0x0f] +
      HEX_CHARS[(h0 >> 24) & 0x0f] +
      HEX_CHARS[(h0 >> 20) & 0x0f] +
      HEX_CHARS[(h0 >> 16) & 0x0f] +
      HEX_CHARS[(h0 >> 12) & 0x0f] +
      HEX_CHARS[(h0 >>  8) & 0x0f] +
      HEX_CHARS[(h0 >>  4) & 0x0f] +
      HEX_CHARS[h0 & 0x0f] +
      HEX_CHARS[(h1 >> 28) & 0x0f] +
      HEX_CHARS[(h1 >> 24) & 0x0f] +
      HEX_CHARS[(h1 >> 20) & 0x0f] +
      HEX_CHARS[(h1 >> 16) & 0x0f] +
      HEX_CHARS[(h1 >> 12) & 0x0f] +
      HEX_CHARS[(h1 >>  8) & 0x0f] +
      HEX_CHARS[(h1 >>  4) & 0x0f] +
      HEX_CHARS[h1 & 0x0f] +
      HEX_CHARS[(h2 >> 28) & 0x0f] +
      HEX_CHARS[(h2 >> 24) & 0x0f] +
      HEX_CHARS[(h2 >> 20) & 0x0f] +
      HEX_CHARS[(h2 >> 16) & 0x0f] +
      HEX_CHARS[(h2 >> 12) & 0x0f] +
      HEX_CHARS[(h2 >>  8) & 0x0f] +
      HEX_CHARS[(h2 >>  4) & 0x0f]
    );
  }
}

NOTE:
If comment last 8 elements compiler finished but after some unexpected long time

Seems the LHS (that grows from the left for each binary op) is recompiled over and over again due to: https://github.com/AssemblyScript/assemblyscript/blob/master/src/compiler.ts#L4661

[dcodeIO]

Indirectly related, because it would aid in implementing calls (here: operator overloads that may be inlined) with less cognitive overhead: WebAssembly/binaryen#1889
