Converts many proc overrides to properly use list/modifiers, lots of other smaller things (#56847)

Converts many proc overrides to properly use list/modifiers, fixes some spots where modifiers should have been passed, calls modifiers what it is, a lazy list, and cleans up some improper arg names like L, M, C, and N. Oh and I think there was a spot where someone was trying to pass M.name in as a string, but forgot to wrap it in []. I fixed that too.
