Yup.  But Remind is significantly more efficient at evaluating

      REM Thu 16 MSG Foo

than:

      REM Thu SATISFY [$Td >= 16 && $Td <= 22] MSG Foo

(In my tests, about twice as fast for the first version compared to
the second.)

And this is the least efficient version:

      REM SATISFY [$Tw == 4 && $Td >= 16 && $Td <= 22] MSG Foo

being about 7x slower than the first version.
