I wrote a prototype programming language + distributed function storage system like this a few years ago.

I stopped when the madness became unbearable.

Exhibit A: https://github.com/mattsta/zlang/blob/master/priv/site_macro...

Exhibit B: https://github.com/mattsta/zlang/blob/master/examples/editor...

(unbearable from an "i created a new unmaintainable language pov, nothing bad about the distributed function storage feature.)
