yes, part of the 'nettles' lib (which comes with cyclone). At least that's true for the old cyclone which came with Pd extended.
not actually true...
cyclone, in Pd Extended, up to version alpha56, used to offer such objects as part of the "cyclone" library - there was no such thing as 'nettles' library then, or any reference to 'nettles' for the end user... see excerpt from the original readme
"* cyclone sub-library, taking care of loading hammer and sickle, and which itself contains: a small set of operators (!-, !/, ==~, !=~, <~, <=~, >~, >=~, !-~, !/~, %~, +=~); an importing mechanism provided by the cyclone class."
After Pd-Extended and under a new maintenance phase, cyclone 0.1alpha57 and 0.2beta got rid of the cyclone library and created a new library named 'nettles', so this is currently available as such only in cyclone 0.2 from deken.
we've been now working on an update of cyclone (cyclone 0.3), and we are reverting this library back to the original name "cyclone", cause we consider that this change was unnecessary and broke backwards compatibility, but it'll will include only these non alphanumeric operators (there are 12 of them, only 3 of which are also in zexy: <~, >~ and ==~)
