Recursive inference error

[dpsanders]

Doing the following on 0.5 gives an inference error, but works fine on 0.4.

using ValidatedNumerics
DecoratedInterval(2, 3, com)

with the branch
https://github.com/dpsanders/ValidatedNumerics.jl/tree/errors

gives the following recursive inference error:

"WARNING: An error occured during inference. Type inference is now partially disabled."
OverflowError()
