+// HACK, XXX(Qyriad): I do not know why the Perl version compatability check on macOS
+// is raising, but as far as I can tell it is wrong.
+// So instead we will replace the "check calling convention and get args" macro with
+// the "unchecked get args" macro.
+// If someone knows why when this file is compiled with Nixpkgs Perl 5.42.0,
+// and then loaded with Nixpkgs Perl 5.42.0, it raises:
+// lib/Nix/Store.cc: loadable library and perl binaries are mismatched (got first handshake key 0x10200080, needed 0xff80080
+// please let me know.
