Can't convert Fixnum to String

[benpickles]

Assigning a numeric query values blows up with "Can't convert Fixnum into String" which seems counterintuitive:

uri = Addressable::URI.new
uri.query_values = { :c => 3 }
# => BANG!

Here's the offending code, I obviously need some Ruby education as I can't see why FixNum wouldn't have a to_str method.

The #to_str method is an implicit coercion. It means, roughly, "Even though I'm not a String, you can pretend that I am if you like." Numbers don't have a #to_str method because they are not String-like. You should call #to_s on your number before passing it to this method. This method rejects Numeric values to avoid bugs with converting floating-point values to Strings incorrectly in an automatic fashion.

Sounds fair enough, thanks for the reply :)
