- overload tolerances for ~~ operator (thanks, Smylers!)
Only test working with switch if switch exists. It's safe to leave the actual definition of ~~ overloading in the module, because in earlier versions of Perl it just gets ignored.
update bugtracker avoid circular loading problems (with a nasty hack) fix spelling error; thanks, Alexandre Mestiashvili!
for example if you say (100 +/- 1/3) with bigfloats, it tries to compute 100 - 1/3 to arbitrary precision oops!
* fractions can now be parsed from strings; they become rationals * all numbers that go in become BigFloats or BigRats
we want numbers (123) not things containing numbers (foo1234bar)
