Well, Spad compiler is supposed to accept program only when it can deduce that the program is type correct. If Spad compiler can not see that program is valid it should reject it. There are some places where Spad compiler accepts code without checking, apparently assuming that it will be checked later. But sometimes there is no later check or it is too weak. Fixing such problems may requre quite large change to Spad compiler. But regardless of effert rexired to fix them, they are still bugs. -- Waldek Hebisch -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
