Serious question: Is it possible to turn ligatures on, but deactivate them for only some of the combinations? Specifically, I want to see =, ==, and === 'as written', meaning 1, 2, or 3 separate characters. Pretty much the rest of them (like <=, or even !=) seem like they're either nice immediately or else I could get used to them. I'd love to know if this is possible at all, possible for some editors / fonts / OS's, etc, or just a non-starter of an idea.
