That is exciting!  Did you see that the README links to a similar
project written in Rust <>?  There’s also
a Rust-based bundler called Packem <>.  Maybe
those two projects are all that we need.  With “mrustc”, the “rewrite it
in Rust” trend looks good for bootstrapping.  :)

Cool.  That looks really promising.  I’m glad to see that the current
“node-build-system” can do the same trick I’ve been doing.
