# fuzion.sys.misc -- miscellaneous system intrinsics
#
module misc is
# intrinsic to get a unique id > 0
#
# this can be used to add a unique identifier to compare instances.
#
# sine there are 2^64-1 possible values, you can safely assume that these are
# in fact unique. Assuming one unique id is consumed every nanosecond, it
# would take more than 500 years before we run out of values
# (2^64/10^9/3600/24/365.25).
