I agree that __eq__ should either work or raise an exception. As to
why __eq__ isn't supported, I haven't written the necessary code to
handle arrays with dtype='bool'.
Offhand, I don't know what specifically needs to be changed to make
sparse matrices agree with numpy's handling of boolean arrays. Many
of the necessary ingredients are already present, but I have not fully
explored this matter.
I created a ticket in Trac for this issue:
Unfortunately, time is scarce for me at the moment, so I can't say
when I'll get around to it.
