Hi,

We, the Erlang/OTP team at Ericsson see the frames proposal as one of
several interesting proposals for
a better than "records" solution. We are currently not working active
with any of these proposals but we have in our long term plans to do
it some day.
I cannot say when that will be but most probably not this year.
