Description

In MetaOCaml, .< e >. is used to encode the quasi-quoting of expression e, whereas .~e is to unquote / escape. These are beautifully encoded in the paper and documentation, but look horrific in actual source-code. Compare:

Typographic ligatures could go a long way towards improving the usability of MetaOCaml; I'd really love to see these supported by Fira Code. (=

(Also see #317 and, especially, #380.)
