I like it. Genuinely, I think APL only reuses glyphs for dramatically different monadic vs. dyadic behavior because there were limited positions available on a Selectric type ball. Many glyphs are reused as-is for multiple meanings, and they had to build some glyphs by overstriking a second glyph on top of an existing one. None of this is a concern these days.

That said, some of the reuses do make sense. ⍴ as monadic shape and dyadic reshape makes perfect sense. In FIXAPL, shape is △ and reshape is ⍴; the symbols have nothing to do with each other. I think that particular separation is a loss rather than a gain.
