Heh...somehow I've stumbled upon Haml/Sass after researching about
static-site generators (StaticMatic supports Haml) and then thought
about Haskell...which has brought me to Hamlet. :-)

The wikipedia page (http://en.wikipedia.org/wiki/Haml#Implementations)
lists severeal implementations, that's why I've asked if Hamlet could
be counted as one?

Same here. No interest in Ruby.

It looks very good. *thumb up*

No rush here. ;) (We'll use Hakyll for now.)
