// Hack to make KDevelop parse QString properly. Q_REQUIRED_RESULT expands into
// an __attribute__((warn_unused_result)) KDevelop's lexer doesn't seem to
// understand, yielding an error and leaving some methods unlexed.
//
// The following first includes <QChar> to get Q_REQUIRED_RESULT defined first,
// then re-defining it as nothing. This causes Q_REQUIRED_RESULT to essentially
// "vanish" from QString's methods when KDevelop lexes them.
//
// Similar reasoning for Q_DECL_HIDDEN, except with Q_OBJECT this time.
