Regarding Gilles’ last comment asking on why I think we should hold off on
putting this functionality in. It seems that we have a lively bit of
discourse here over the different varieties of offering the consumer the
best options as to how to provide a uniform randomness generator to TEXT.
Thus I’m going to plan on doing a 1.1 release shortly following 1.0 that is
dedicated to this work. Does anyone have any objections to that?


Sounds great.

I'd rather we focus on getting all the right stringy wordy stuff "moved"
from LANG to TEXT for 1.0. Then RERO! We have momentum now. I do not see
the need for a bigger bang 1.0 for TEXT. We can add random code for 1.1.
That sounds like a perfectly reasonable roadmap.
