</span>I think that if we go down this road, @behavior(lazy) or just @lazy is strictly superior. We already have the @ sigil for attributes; we don't need to introduce another sigil for no apparent reason.<br>
<br>
(But unless we're going to use the latter syntax and say "all @s are behaviors, we just haven't formalized func/type/etc. behaviors yet" so we finally have an idea of what @ means, I don't think either of these syntaxes is better than the one proposed.)<br>
