I do not think that HAML or SASS add any abstractions that Ur/Web with a full 
CSS support would not already have.  So in that sense implementing them would 
not gain anything.  If Ur/Web gained a sort of a typed macro system allowing 
user level implementation of SASS/HAML as a syntactic DSL that would be really 
interesting.
