To expand upon what Corey was saying, `box` is basically a huge special-cased hack right now. I'm surprised that a mention of `box(GC)` is even included in the tutorial. Someone tell Steve to rip that out. :P
We'll be clarfiying how best to use `box` before 1.0. In the meantime, just don't use GC. Like, at all. You don't need it! :) On Wed, Jul 2, 2014 at 10:39 PM, Corey Richardson <[email protected]> wrote: > The full syntax is: "box" ["(" EXPR ")"] EXPR > > The first expression is the "boxer", or where the result of the second > expression will be stored.
