This backwards-incompatibility bugs me. Why don't we set dtype=None as the default for ndfromtxt & mafromtxt and tell people to use these functions instead (I'm pretty sure nobody knew they existed, so we can break them without upsetting anyone)(of course, there's gonna be a counterexample as soon as I post that).
