Local variable assignment resolves incorrectly

[tim-styra]

Expected Behavior

A locally-defined dictionary should be able to hide a globally-imported dictionary, e.g. baz in the following package should be true.

package foo
import data.bar

baz {
    bar := {"qux": 7}
    bar.qux == 7
}

Actual Behavior

baz above is undefined because bar.qux is undefined. Presumably this happens because when the compiler resolves the symbol bar it does so with data.bar instead of the local variable bar. So the compiler sees the rule above as:

package foo

baz {
    bar := {"qux": 7}
    data.bar.qux == 7
}

Steps to Reproduce the Problem

Evaluate the policy above.
