/**
 * @assertion Let E be an export directive that refers to a URI via the string s1. 
 * Evaluation of E proceeds as follows:
 * First,
 *   - If the URI that is the value of s1 has not yet been accessed by an import
 *     or export directive in the current isolate then the contents of the URI are
 *     compiled to yield a library B.
 *   - Otherwise, the contents of the URI denoted by s1 have been compiled into
 *     a library B within the current isolate.
 * Let NS0 be the exported namespace of B. Then, for each combinator clause
 * Ci, i in 1..n in E:
 *   - If Ci is of the form show id1, ..., idk then let NSi = show([id1, ..., idk], NSi-1).
 *   - If Ci is of the form hide id1, ..., idk then let NSi = hide([id1, ..., idk], NSi-1).
 *   
 * For each entry mapping key k to declaration d in NSn an entry mapping k
 * to d is added to the exported namespace of L unless a top-level declaration with
 * the name k exists in L. We say that L re-exports library B, and also that L
 * re-exports namespace NSn. When no confusion can arise, we may simply state
 * that L re-exports B, or that L re-exports NSn. 
 * @description Checks that the combined effect of show and hide combinators in an export
 * declaration is calculated as specified. Test imports 2 libraries that declare the same
 * names assigned to different values, but their exported namespaces are filtered using
 * show and hide combinators to avoide name conflict.
 * @static-warning
 * @note Most of this is already covered by 1_Imports_A02* tests.
