Hopefully fixes #359. * spot/misc/trival.hh: Declare a global operator==(trival,trival) that replace the specialized operator==(bool,trival), and the in class trival::operator(trival), thanks to the implicit construction from bool to trival. Make the repr_t/value_t constructor explicit, are those are mostly internal to the library and may cause conflicts. * spot/twa/twa.hh: Adjust to construct trival explicitly. * python/spot/impl.i: Since Swig/Python does not support global comparison operators, implement a member version, supporting only __eq__(trival,bool) as before. * tests/python/setacc.py: Adjust erroneous code. * tests/python/trival.py: Add test cases.
