So, auto(x){ x->first < 0 } returns bool, and auto(x){ x->first < 0; } returns void?
Did I say that? I didn't mean to say that.
Yes, it sounded like that was maybe what you meant (in another message in this thread - quoted below). So what does the version with the semi-colon return? Or would the semi-colon be a syntax error? Darren -------------- Yes, of course it's an expression. We make a provision that a lambda expression can end with a simple expression in which case that is its return value. It could be made into a statement and a valid function body like this: auto(x) { x->first < 0; } but then such a statement normally does *not* return, and the semicolon adds a little confusion, one more character, and nothing of value.
