-----------------------------------

I'm not sure exactly which version it changed in, but it's a problem in later
versions of Ruby (which we should support).
{quote}
it changed in 1.9.1 (which is early in the 1.9 line). agreed that we should be
handling this.
{quote}
Users will only get unexpected results with unions of double and long if they
do equality tests. The semantics of equality between Bignum and Float changed
in Ruby itself, so I don't think we need to make any changes in Avro.
{quote}
I'm not sure I follow. The test looks like it declares a default value for the
union to be an instance of the double type. It then makes a record that relies
on that default and finds that the values are not equal. Shouldn't both of them
be Float?
