There are 2 different syntaxes for initializing something with one value:

(a) T x = y;

and

(b) T x(y);

assuming T is a type (possibly a class), and y is an expression (whose type
may or may not be T).

What's the difference?

A practical question: How do I know when I need syntax (a), and when I need
syntax (b)?

And a philosophical question: Why is there a difference at all?

Thanks,

Robert
