Definition-level parent-child references-by-name fail in 1.4.0 but not in 1.3.5

A buildfile like this one:

define "root" do
define "child" do
puts project('root')._('foo.resource')
end
end

will work fine on buildr 1.3.5. However, it fails with a circular dependency error on 1.4.0 RC4:

RuntimeError : Circular dependency detected: TOP => root => root:child => root
/private/tmp/buildr-problem/buildfile:3

I don't think this need block the release because the following workaround succeeds in both:

define "root" do
define "child" do
puts project.parent._('foo.resource')
end
end
