Lambda syntax, etc

Jarrett Billingsley:

This looks better to me (but I don't know if this is the best syntax, it's just an idea):

// syntax for lambda that contains a single expression, implicit return (this is the most common case):
auto r = find!(a => a.Weight > 100)(range);

// syntax for lambda that contains one or more statements, no return, side effects only:
something({ a, b :: stmt1; stmt2; });

// syntax for lambda that contains one or more statements, with side effects and return:
something({ a, b :: stmt1; return foo(); });
