 Look at your macros in a whole new scope.

Hexstream/bubbleoperatorupwards
 A function that "bubbles an operator upwards" in a form,
demultiplexing all alternative branches by way of cartesian product. This
operation is notably useful for easy implementation of certain kinds of
shorthand notations in macros. A cartesianproduct function is also exported, as
it's needed to implement the main function.

Hexstream/parsenumberrange
 Parses LOOP's convenient "forasarithmetic" syntax into 5
simple values: from, to, limitkind (:inclusive, :exclusive or nil if
unbounded), by (step) and direction (+ or )). Further related utilities are
provided. Intended for easy implementation of analogous functionality in other
constructs.

Lambda, ready for ASDF and Quicklisp.
