Since then, Proto has found application in the 15redesigned and improved Spirit-2 and the related Karma library. As a result of 16these efforts, Proto evolved into a generic and abstract grammar and tree 17transformation framework applicable in a wide variety of EDSL scenarios. 18 19The grammar and tree transformation framework is modeled on Spirit's grammar and 20semantic action framework. The expression tree data structure is similar to Fusion 21data structures in many respects, and is interoperable with Fusion's iterators and 22algorithms. 23 24The syntax for the grammar-matching features of `proto::matches<>` is inspired by 25MPL's lambda expressions. 26 27The idea for using function types for Proto's composite transforms is inspired by Aleksey Gurtovoy's 28[@http://lists.boost.org/Archives/boost/2002/11/39718.php "round" lambda] notation. 29 30[/=================] 31[heading References] 32[/=================] 33 34[:[#boost_proto.users_guide.resources.SYB]Ren, D. and Erwig, M. 2006.
