wonder why?
1. time1 \approx time2
2. F3 doesn't work at all.

In hansl you cannot "take the address" of something that's not a
variable in its own right. This is not specific to bundles: the same
would go for, e.g., "&m[,1]", where m is a matrix -- not a valid
expression. In this respect hansl differs from C, but that's the way
it is.
