It is possible to take this too far.. https://imgur.com/a/5NP6FWx

But it did keep me entertained for a bit.

I've recently tried Emacs for a few weeks and prettify-symbols-mode doesn't look nearly as good in my opinion, as the scale and style of the symbols isn't consistent with the font. Also I never got any symbol out of it in any situation except an arrow and lambda.

I'd much prefer if Emacs just supported actual ligatures.
