- * ### Subclass

- * In \a assign() methods you can use event handlers with 0 or 1 arguments,

- * ### Aggregate
- *
- * Create instance of %PIParseHelper and construct it with target object.

- * In \a assign() methods you can use event handlers with 0 or 1 arguments,

- * Assign methods that receive lambda-functions can`t accept direct lambda (\"[](){}\")
- * with template type deducation because of C++ specific. E.g.
- * \code assign(1, [this](SomeStruct s){}) \endcode
- * doesn`t compile, but these variants allowed:
