Let me weave you a tale of wondrous pins, the likes of with not before seen in the Vortex! But seriously, [P-------] is clearly the correct code for a single pin in NE corner, right? And yet, I've successfully found the mythical [P?------], [Pj------], and [PoPn----] in Signal Generator. How scandalous! It allows me to create such abominations as is attached in the image. Notably, any color that exists as a second character turns the shape code to 'null'. Shape Analyzer clamps it back to [P-------], which is the only equality that works after a shape analyzer. Apparently, an IF gate in diode does much the same. If Shape Analyzer clamps weird pin colorations, Signal Generator could do the same and prevent invisible inequalities.
