There is a small bug when casting is done with a class member. As an example:

class Simple 
{
    int p;
  public:
    double get() {return p;}
};

yields

class Simple 
{
    int p;
  public:
    double get() {return static_cast<double>(this->p)p;}
};

An additionnal p is added after the cast, making the resulting code uncompilable.

Other than that, it is a great project !
