Basically everything it does for the Lua modules. Setting _M, _PACKAGE,
_NAME, setting the global. But more important I'd like the binary module
to still work well on environments where module has been replaced with
another implementation.

For the moment, if some particular Lua users replace "module" with a
custom version more adapted to its environment (for example in some
project I'd like "module" not to set the global tables, only register
the module in package.loaded), Lua modules will still work with that
environment, but binary modules may fail to. Calling "module" will
ensure that the code provided by the user get called, the code necessary
to adapt the module to the new environment "from the inside".
