As a developer, I have spent years writing and learning to parse the meaning of sequences like ==, ===, <=, ~=, and so on. For nearly all of us, the ligatures in this font are completely new. I think it's a creative and interesting idea, but it means re-training my brain to recognize them, which would take time.

And even if I could get my preferred editors to work with it, I would see the traditional symbols when reading code on the web, or pairing with another developer who does not use the font. It seems like a barrier to understanding, something that by nature developers strive to eliminate.

I'm torn. This idea could be something that changes how we all express code symbolically, or it will just become a fad that a tiny percentage of developers will insist on using, to the frustration of everyone else.
