[Haskell-cafe] built-in lists vs inductively defined list

Hi,

 

Can someone tell me if would be any difference (beside syntax) between the
built-in Haskell list with [] and : and lists given by a inductive datatype
definition like

 

data List a = Nil | Cons a (List a)

 

This is, is any of the compilers doing some special optimizations for the
built-in lists?

 

Best
