    ApiAnnotations : BooleanFormula construction discards original
    
    Summary:
    The MINIMAL pragma is captured in the parser using a BooleanFormula.
    
    The constructors (mkBool,mkAnd,mkOr) are smart and try to minimise the
    boolean formula as it is constructed.
    
    This discards the original information, making round tripping
    impossible.
    
    Note: there is another version which provides a more API Annotations
    friendly version of the MINIMAL pragma, but this requires changes to
    haddock, which will cause problems for 7.10.2.
