Currently, the do_exist function that performs the checks for unused types declared with using declarations, only matches the name of the using declarations. The means that some unused using declarations are not detected. For example having both a 'using Maybe;' and a 'using MaybeLocal' and only using MaybeLocal would not be reported. This commit attempts to take into account the above mentioned case and also others where the name of the using declaration type is used in name of a variables or function call. For example, 'using Just;', will now be reported as unused even if there are calls to the FromJust function.
This commit removes the unused using declarations reported by lint-cpp.
