v2.001001

  - Import all constructor functions by default
    (via 'use List::Objects::WithUtils')

  - Add 'immhash' immutable hashes

  - Add 'immarray_of' and 'immhash_of' immutable type-checking lists

  - New array methods: delete_when(), end(), inflate()

  - hash()->clear returns the hash object

  - Immutable array behavior should now work consistently across any
    perl version; no longer mucking about with Internals::SvREADONLY

  - Immutable & type-checking behavior moved to roles

  - Role::WithJunctions moved to Role::Array::WithJunctions

  - t/ reorganized to be slightly more managable
