[Grace-core] Fwd: [Grace-interest] Progress on New OO language "Grace"

[Eric Tanter]

Hi all,

Sorry I've been really silent on the list, because of lack of time. But now I see this remark of Sophia and I couldn't agree more. It reminds me of the invited talk of Dave Ungar at ECOOP (09?), where he talked about designing languages top-down by considering values->principles->practices, instead of going by example, or bottom up.

In a nutshell:
values (what you care about, what you want, what you like)
principles (general rules for achieving values)
practices (specific things to do)

but the best is to (re-)watch Dave's talk (available online).

It would be really helpful to have (and discuss) the values/principles/practices statement of Grace.
