Description

#44 describes using a Proxy to import an arbitrary number of empty prototype objects with no code size overhead on the JS side. This seems to perform well enough in some initial tests on V8, but if there are performance concerns about using a Proxy like that, we could standardize some new API/mechanism to achieve the same end.

Research direction

Start by reading issue #44 and the initial V8 performance results referenced here. Establish whether the Proxy approach has unacceptable performance, then determine what a standardized mechanism for importing arbitrary empty prototype objects would need to provide; completion would require an agreed API or mechanism, not just another performance observation.
