-0 on this one. It's going to confuse an awful lot of newbies when
they write Decimal.from_float(1.1) and get
Decimal('110000000000000008881784197001252...e-51').
Also, why not just extend the Decimal() constructor to accept a float
as the argument? Why have a separate from_float() method at all?

+1 on this.
