Ooh, yes :(
'(use X)'
Represents the use of the value of X. It indicates that the value
in X at this point in the program is needed, even though it may not
be apparent why this is so. Therefore, the compiler will not
attempt to delete previous instructions whose only effect is to
store a value in X. X must be a 'reg' expression.
Partial revert is in works.
