I remember @hahnjo and @zygoloid discussing that the odr-hasher is probably not the best way to has template arguments because the hasher would not take into account semantic aspects of template arguments. For example, a fully qualified template argument would not compare the same to a non-qualified one. We might need to implement our own folding set logic.

@hahnjo, could you help me out dig that discussion.
