Oh, I meant HsColour instead of HsSyn.

Personally, still do not see the big benefit for all that work, and I'm still somewhat worried that a mechanism that is not used by default (I'm talking about unliting with an external command) may start to bit rot. But as long as you are commit to keep `-pgmL` intact, I'm ok ;). I think in the end it's best to go with the solution that works best for GHC-HQ.
