/*!
|
|
* \file reflector-boosthana.h
|
|
* \brief Contains generic functions relying on Boost.Hana which can replace the code which would
|
|
* otherwise had to be generated.
|
|
* \remarks
|
|
* These functions use boost::hana::keys() and boost::hana::at_key() rather than the "plain"
|
|
* for-loop shown in the introspection examples of the Boost.Hana documentation. The reason is that
|
|
* the "plain" for-loop involves making copies. This costs performance and - more importantly - prevents
|
|
* modifying the actual object.
