Why not use a roll-your-own if replacement?
_if: :if
if: func [condition block [block!] /quiet /local result] [
result: _if condition block
either quiet [
exit
][
return result
]
]

== false

Note that you cannot redefine if UNLESS you preserve its original behavior
as the new, reassigned if's default behavior, because there are some
mezzanine functions that expect if to return some value. These functions
may fail if your reassigned if does not act as they expect.
That's why my reassigned if preserves the behavior of REBOL's original if
as its own default behavior when it is called without the /quiet
refinement. The mezzanine functions will be served the result they expect.
