Please watch the tone. It is borderline abusive and dismissive.

-1 I am solidly against this.  The other inputs to Fraction() are exact conversions.  The proposal works against a core concept behind the fraction module. 

Also, my expectation for Fraction("0.0015") would be to give Fraction(3, 2000), the same as would be given by Fraction(Decimal("0.0015")).

Perhaps this tracker issue should be closed and moved to python-ideas.  The notions are currently too immature to warrant more core developer time.

Also, it would be nice to have research into what other languages and libraries do for fractional approximations of decimal strings.
