- Update to 0.012:
  - Work around Perl core bug (Perl RT#68590) regarding leakage of %^H into
    modules being loaded
  - Work around Perl core bug that made a failed module loading appear
    successful when re-requiring the same module
  - Duplicate is_string() from Params::Classify, rather than importing it,
    to avoid circular dependency problems
  - Duplicate minimal exporting behaviour from Exporter, and avoid using the
    "feature", "warnings", "strict", and "parent" pragmata, to allow for
    possible future use of this module by any infrastructure module
  - Document core bug workarounds
  - Document module name syntax more prominently, and discuss the state of
    Unicode handling
  - Tweak documentation of use_package_optimistically()
  - Test behaviour with tainted module name
  - Test lack of unwanted eval frame around require
  - Give test modules more meaningful names
- Drop now-redundant dependencies on perl(Exporter), perl(Params::Classify)
  and perl(parent)
- BR: perl(strict) and perl(warnings) for test suite
