26Haskell in vim with scientifica:
27![haskell_ligs](https://0x0.st/sT8a.png)
28
29Credits go to [romeovs](https://github.com/romeovs/) for the haskell plugin.
30Credits go to [ehamberg](https://github.com/ehamberg/vim-cute-python) for the python plugin.
31
32Both plugins have been modified (haskell.vim especially) to play well with scientifica.
33If you need ligatures for other languages, just open an issue, with the language and the ligature sequence.
