An error will be signaled if @$s.actingUser is not
of Class Root. (In the usual Muq configuration, the only
instance of Class Root is .u["root"].)
This construct allows you to write a function which executes
with essentially no security restrictions at all.
Obviously, this is very dangerous and should be done very
carefully indeed and only when truly needed: The surface
syntax is intentionally clumsy to discourage frivolous use.
When practical, use the somewhat less dangerous
rootAsUserDo: See section rootAsUserDo.
This construct saves the current value of jS.j.privs,
an internal C-level privilege word, on the loop stack, then
sets the omnipotent bit in jS.j.privs. Upon
exit from the construct, the original value of
jS.j.privs is restored.
See section rootPushPrivsOmnipotentFrame. See section pushLockframe. See section asMeDo.
