library, which implements a form of <emphasis>lambda abstractions</emphasis> for C++.
The term originates from functional programming and lambda calculus, where a lambda abstraction defines an unnamed function.
The primary motivation for the BLL is to provide flexible and
convenient means to define unnamed function objects for STL algorithms.
