Hi all,
since release is near, I feel it may be a good time to propose a
backward-incompatible change that IMHO sooner or later we'll have to make:
originally, we had "|" and "&" for logical operations. Then, when
matrices
appeared, we used the same operators for concatenation (mostly, because
that's what everybody else uses). At the same time, we also support "||"
and "&&" for logical operators. This, I think, creates an ugly ambiguity
which should be resolved by specialising "|"-"~" for concatenation and
"||"-"&&" for logical operations.
Do you agree?
