This is actually a great point.
"¡Hola, mundo!"
Note that the sentence is one character shorter than the corresponding phrase in english (`"Hello, world!"`) - this kind of efficiency is quite common when you write in Spanish. Also note that the extra space won by removing a character was then used to add a pre-exclamation flag (`¡`). This flag is a neat optimization to ensure that the interpreter knows to prepare for an exclamation ahead of time.Better interpretation, pronunciation, efficiency. Why are you not writing Spanish today?
