Yay Perl6. Took me a while to figure out the magic incantation, because the Perl6 documentation is nigh incomprehensible. Also, Rat() ignores the epsilon parameter if it's called on a rational. Sometimes, you'd like to find a fraction that's an approximation of another fraction without mashing it down to a float first.
