No. It's tempting, but adding __cmp__ to complex non-value-like
objects tends to get in to trouble when people make different
assumptions about what equality means: is a locked Branch equal to an
unlocked Branch pointing to the same thing?

Better just to use has_same_location, or get the base locations and
uniquify on that.
