I also see my phone auto-corrected as heal instead of heel ... :)
To John, albeit selfishly :), I'd love to see structs prioritized over
fixnums and maybe some of the other things (reification would be great too
and would go a long way in reducing bloat due to boxed numerics). Is there
something akin to public voting on prioritization of features that Oracle
agrees to dedicate resources to? Maybe I'm overestimating demand, but I
think structs would get a lot of backing.
