Subject: [Caml-list] non-optional labels in signatures

Hello,

This is certainly a question for Jacques Garrigue. I'm asking out of pure curiosity if there's a particular reason why non-optional labels in signatures don't have the ~ ? Is to save a keystroke ? 

(I happen to make the error of putting them in signatures fairly often) 

Best, 

Daniel
