..and this is PRECISELY why there's a shortage of Mercurial hackers on
Windows. The above takes at least an hour for a new user to figure out,
if not a whole day, but actually usually puts them off the idea of
hacking the source entirely well before that.
In my scheme, you "install" -one thing- which affects nothing else on
your system, and you can hack the Mercurial source and run it in-place
-without ever even running a build step-. Download, unzip, hack, run.
Given a broadband link, a new user can test a bugfix or debugging patch
in less than 5 minutes.

Mathematics is the supreme nostalgia of our time.
