Programming languages are limited to relatively few characters. As a result of a limited character set, combined character operators surfaced quite early, such as the widely used arrow (->), comprised of a hyphen and greater sign. It looks like an arrow if you know the analogy and squint a bit.
Composite glyphs become especially problematic in languages such as Haskell which utilize these complicated operators (<-, ::, =>, -<, >>= etc.) extensively (over 100 in lens alone!). Prettified code improves readability considerably - some Haskell programmers have even resorted to unicode symbols (ie. ⇒, ← etc.). This opens a whole new can of worms. In addition to encoding/compatibility problems and all the reasons it never worked out in APL, these symbols are one-character-wide and therefore eye-strainingly small.
Hasklig solves this problem the way typographers have always solved ill-fitting characters which co-occur often: ligatures. The underlying code stays the same — only the representation changes.
