libsigc++ ships with basic lambda functionality and the sigc::group adaptor, which uses lambdas to transform a functor's parameter list.
The lambda selectors sigc::_1, sigc::_2, ..., sigc::_9 are used to select the first, second, ..., nineth argument from a list.
Operators are defined so that, for example, lambda selectors can be used as placeholders in arithmetic expressions.
