A file can now declare that a default order is either inc or dec, and this will be reflected in short hand type syntax, inc is still the default if undeclared
So:
default order dec
register bit[32] t (* Declares t as a decreasing vector, starting at 31 on the left and decreasing to 0 *)
default order inc
register bit[32] o (* Declares o as an increasing vector, starting at 0 on the left and increasing to 31 *)
It is presently possible to change the default mid-file; this is almost certainly bad and I will turn it into an error soon.
