I feel the same way.

I do think I would enjoy programming in a language that used a slightly more extended set of real characters, as long as we had solid editor and font support so typing and viewing them wasn’t going to be an issue for anyone. For example, I’d like to finally have ≠, ≤ and ≥ lining up neatly with =, < and > in my code! I could imagine a few other carefully chosen and easily recognisable symbols, such as ∈ and true arrows, being helpful for readability as well.

But the world speaks in Unicode these days, so assuming there was adequate tool and font support, I think writing these characters for real would be much better than relying on ligatures. Even where ligatures are supported, they tend to use awkwardly wide glyphs to replace multi-character combinations so they don’t break alignment in a monospace font, and sometimes the fonts with programming ligatures seem to join certain combinations in bizarre ways just because they can, even when there’s no apparent need for it.
