Issues Resolved

beartype.vale.Is[@beartype(...)].** The functional beartype validator API (i.e., the beartype.vale.Is[...] factory) now permissively accepts any low-level callable accepting one parameter wrapped by a higher-level callable, resolving issue #104 kindly submitted by the munificent typing maestro @dycw (Derek Wan). Specifically, the beartype.vale.Is[...] factory may now be subscripted (indexed) with any validation function wrapped by a decorator wrapper wrapped by the standard @functools.wraps decorator, including any @beartype-decorated validation function. Thus is the circle of validation complete. Cue Hakuna Matata.
setup.py circularity. Our top-level beartype.__init__ submodule no longer implicitly imports from any beartype submodule (except the guaranteeably safe beartype.meta submodule) when imported at install time by our root setup.py script, resolving issue #108 kindly discovered by @posita in a distressing comment embedded within the murky depths of PR #103. Specifically, setup.py now dynamically populates the standard sys.modules list with a fake beartype.__is_installing__ "module;" beartype.__init__ then detects the presence of that "module" and avoids implicitly importing from unsafe beartype submodules. In short: insane hackery. That's just how we roll.

Import isolation. The test_package_import_isolation() integration test minimizing importation costs by ensuring that the first import of the top-level lightweight :mod:beartype package does not accidentally import from one or more heavyweight third-party packages now omits the third-party typing_extensions module from scrutiny. Thanks a bundle of crypto that I do not have to @posita for his deep profiling sacrifice at #103! @posita: still dah best in 2022.
