someone here mentioned they use {} or "do..end" based on whether the
block has side effects or not.

And the precedence comes into play when the method call preceding the
block has arguments that aren't in parenthese, then {} (the higher
precedence) will "pick off" the last arg from the method call (p 356
pickax)
