Beyond that boolean datatypes worry me semantically - not the domains,
which people seem to be able to live with, but real boolean types.
Assuming that c1 is a boolean column, I would expect to be able to
do this:

where t1.c1 or t1.c2 = 12
or
set t1.c1 = NOT t1.c1

That's going to require applying force and violence to Claudio's
well beloved parser.
