It’s not like ‘way’ smart in that it can combine all parts possible, but it is pretty decent. In general yo…

Also remember that everything is an expression (there are no statements) so everything evaluates to some kind of value.

This is why there is no return statement - functions have to evaluate to a value just like expressions, so they automatically “return” the last value they evaluated.
