I cited the relevant bugzilla.mozilla.org bugs recently in public-html:
https://bugzilla.mozilla.org/show_bug.cgi?id=259935#c0
is the place where assignment to a variable came up; it links to:
http://us.js1.yimg.com/us.yimg.com/lib/g/ylib_dom.js
See also:

The masquerades-as-undefined approach works equally well on such
sites, and it works better in theory, except for the nastiness of
violating ECMA-262 rules, which matters not only for conformance
purity but also for any implementations modeled on the spec in ways
that make it a chore to support masquerades-as-undefined.
Anyway, I wanted to cite the bugzilla links for anyone interested in
the history.
