Monoid: A coding font with ligatures

Nice! I've got ligatures in my Haskell with the default spacemacs set up, this font looks really nice.

How is it implemented? One of the problems with Haskell code is that there are quite a few instances where the examples given are within a larger infix operator for example:

>-> from pipes looks like this >→

Still a net win, but is there anything that could be done about it?

Too bad emacs doesn't do ligatures. :-(
