Con Has a heavier appearance than Fira Code or Monoid
Con Lacks !=
Some coding fonts with ligatures, like Fira Code, turn != into ≠, but Hasklig does not. The reason for this is that Hasklig was designed for Haskell code, and so turns /= into ≠ instead.
Con No support for many editors, including emacs
Unfortunately, not supporting emacs is the number one reason I don't use this font all the time.
Con Very cute but not WYSIWYG
You want to see exactly what you've typed, not have your brain have to do a little dance every time you see one of these artifacts.
