Return TYPE if no type compatible with TYPE has been seen so far, 
otherwise return a type compatible with TYPE that has already been 
processed.

Or,

Find a type compatible with TYPE among those that have been processed, 
and return it.  If none can be found, register and return TYPE.

(It took me two/three iterations to read your message too.  You want to 
quote "either", "an" and "that" probably...).
