The YNVM is a response to the rigidity inherent in current programming languages and environments, which present significant barriers to the construction of dynamically reconfigurable systems. It provides extreme late binding of system/language features, unconstrained application involvement in the management and use of meta-data, maximally open reflective features, and elevates concrete implementation (compiled code) to first-class status by providing dynamic (re)compilation of any part of a live system without loss of efficiency. It is compatible with existing code bases, and applications built on top of (or next to, or under) it can be made highly reconfigurable with minumum effort and negligible overheads.
