+a simple c-like language with support for if/else-statements, while-loops and the standard arithmetic (+, -, /, *) and comparison expressions (<, >, <=, >=, ==, !=). also, post increase/decrease expressions (++, --) are supported. Assignments are allowed in expressions, but they are only allowed on the right side of arithmetic/comparision operators if they are put inside parenthesis

 integers and booleans.

 // and /* */ comments are allowed.
 
+(For compilation to work the Bool type in Abssyntax has to be removed so the internal haskell type is used)

+if with else: 1 conflict
+An if statement before the else could be reduced to an if statement lacking the else, but the correct thing is to shift it onto the stack.
