import.meta and TC39 process as a whole

I would be comfortable with `module.import()` and `module.meta` instead of
`import()` and `import.meta`, simply because the name `module` more
automatically describes the module specific "global" object than `import`
does. Also, it more explicitly communicates that the "import" is specific
to the module and hence how it is able to use its folder path etc. as root,
for example. I would be comfortable if everything else about them stayed
the same as the proposals though
I would like to see the `module` object and `module.import()` included in
the "Alternative solutions explored" section in the dynamic imports
proposal: https://github.com/tc39/proposal-dynamic-import along with the
explanation that `module` could be the module specific "global" object
instead of `import`, along with `module.meta` as an alternative to
https://github.com/tc39/proposal-import-meta . I think it is the most
compelling of the "alternative solutions".
