I develop Hasklig, and have enjoyed the discussion about the pros and
cons of ligatures in coding fonts. However, I really must protest this
line of reasoning since it is based on false premises.
As an opentype feature, ligatures have nothing to do with the 'fi' and
'fl' unicode points, (which are legacy only, and heavily discouraged by
the unicode consortium), or with unicode at all. The encoding of the
file could be pure ASCII for all the ligatures care. The font used
changes how the text looks, and nothing else.
When speaking of special unicode symbols in code, I agree with most
objections raised against them :)
P.S. Sorry for potential repost - I'm getting automatic rejects
