Obligation:
mainModule Main 
module Main where {

data Main.Char = Char MyInt ;

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

data Main.Maybe a = Nothing  | Just a ;

data MyInt = Pos Main.Nat  | Neg Main.Nat ;

(1) BR (EQUIVALENT)
Replaced joker patterns by fresh variables and removed binding patterns.

Obligation:
mainModule Main 
module Main where {

----------------------------------------

(3) COR (EQUIVALENT)
Cond Reductions:
The following Function with conditions
"undefined |Falseundefined;
"
is transformed to
"undefined  = undefined1;
"
"undefined0 True = undefined;
"
"undefined1  = undefined0 False;
"
