module amodule

// This tests whether _test.v files can be *internal* to a 
// module, and thus have access to its guts.

// NB: the function test_private_isub() is defined both here
// and inside internal_module_test.v . That is done on purpose, 
// with the goal of ensuring that _test.v files are compiled 
// *independently* from each other.
//
// _test.v files should *only* import all the other normal .v 
// files from the same folder, NOT other _test.v files from it.
