I don't quite get this point:
the only way I see to change k while the comprehension is running would be
another tread, is this the concern?
Even so: assuming Array{Any,2,2} won't save against a reassignment to k to
an array of shorter dimension, or a scalar, or a string...
I can't see any gain in assuming Any instead of Float64 but I can see the
nuisance of having an asymmetric behavior between different scopes.
