That's not really related to my question about customizations, and there is no aliasing going on in any case. The user will see ¬ in both cases, but they will be different underneath. `prettify-symbols-unprettify-at-point' set to 'right-edge is really helpful in this case, incidentally.

It's a visual clobbering, but yeah, I know what you mean. Typically users will not have such functions or variables, but it would be good to distinguish them in a way that makes their ephemeral nature clear. Right now they aren't. The "shadow" face looks like a great candidate. Or maybe there can be a new "prettified" face, similar to "shadow"? It should have colors and decorations that are not used much otherwise, so "dimmed out" like the "shadow" face might be ideal. Ted
