Update to 0.112. From the changelog:

- rebuild MANIFEST, adding two forgotten files

- When printing diagnostics, differentiate the type of a blessed object
  from the name of the class itself (RT#78288, caused by changes to how
  blessed objects are treated in 0.109) (thanks, Karen Etheridge)

- Typo fixes (thanks, David Steinbrunner)

- Fixes to clarity and accuracy of documentation (thanks, Michael Hamlin)

- Add metadata links to repo and issue tracker

- Added obj_isa for testing ->isa without falling back to ref($x)

- Added the *experimental* ":v1" export group to skip importing
  Isa, isa, and blessed
