Whoa -- this is VERY good news for me, I always wanted all of
this being possible in REBOL.
Orthogonal persistency is an extremely nice feature to have,
this also suits the philosophy of REBOL down to the ground,
in my opinion, and the example code you gave did look very
elegant - with one exception. 'tmp as a word is almost
devoid of any meaning and used quite ambiguously in the
example, so at first glance I had a hard time to follow what
was going on in the nested part at the end.
Perhaps assigning different words like 'btn1, 'btn2, ..., to
the face instances would make things clearer.
But thanks for the info, this already made my day (1:26 am)
...and happy birthday!
