So I’m far away from being normal.

I think that a functional language with dependent types is a great thing but I 
doubt that it is good to extend Haskell in this regard since the presence of 
bottom is problematic in the context of dependent types.  And if you want to 
use the power of dependent types effectively, you’ll often have to use some 
kind of specialized editor which removes some of the additional work which is 
introduced by using dependent types.  So I think, it’s more reasonable to 
improve a system like Epigram to get a system which is applicable to real 
world problems.
