Description

When the Haskell generator generate the data type like this

enum Sample1

{ A = 0, B = 1, C = 2 }

enum Sample2

{ C = 0, D = 1, E = 2 }

Output will be like this

data Sample1 = A|B|C
– ...
data Sample2 = C|D|E

And this will make a compile error "Multiple declarations of ‘C’".
So I modified this to generate like this

data Sample1 = Sample1_A|Sample1_B|Sample1_C
– ...
data Sample2 = Sample2_C|Sample2_D|Sample2_E
