There is a need for flonum operators that overwrite existing
flonums. This will reduce the garbage produced by such calculations.
(let ((a 0.0))
(fl+! a 3.0)
(fl+! a 2.3))
should have only one pointer value given to variable a
during the entire execution of the let, but the value final value of a should be 5.0.
