 For next release
 ^^^^^^^^^^^^^^^^
-- fix push() pop() of vera registers
 - if passing a subroutine or label name as an uword argument, without &, add  the addressof automatically
 - convert the sounds in cx16 tehtriz to use the psg module instead
 - notify petaxian that it could use the psg module too?
