-    deal with deprecation of apostrophe as a package separator
-    
-    this package for some reason includes its own copy of Test::More
-    which includes isn't, the code also uses apostrophe as a package
-    separator. This usage was deprecated in perl 5.37.9, and support
-    for it will be removed sometime in 5.39.
