True, but I bet the majority of template constraints are in this
form. The wiki page you linked also says that clauses that are
not in CNF can be rewritten in CNF, but doing that automatically
in the compiler would probably be difficult, bug-ridden, and
annoying for end users.
Are you familiar with Nim's implementation of concepts? I think
somebody actually implemented something close to this in D using
inheritance and introspection.
