| Subject: | 0.05: keys on reference is experimental |
When running the test suite with a newer perl (e.g. 5.20 or 5.21), then following warnings appear:
keys on reference is experimental at /tmpfs/.cpan-build/Test-Approximate-0.005-VcszZu/blib/lib/Test/Approximate.pm line 95.
push on reference is experimental at /tmpfs/.cpan-build/Test-Approximate-0.005-VcszZu/blib/lib/Test/Approximate.pm line 104.
As the same constructs do not work at all for older perls (5.12 and older), it's best to replace it by keys/push calls on non-references (i.e. keys %$foo instead of keys $foo).
