Revision history for HAMT

0.04    2026-11-04
        - Fix the ABI selftest, which let go of a struct the object owned when a store
          into a borrowed transient failed, and read a copy that had not been made
        - A test door fails the n-th allocation, and every operation is starved through
          it: each allocation it makes fails once, with nothing leaked and the inputs kept
        - Test every checker rule on a trie or a vector broken that one way, the persistent
          put and delete, a handle cloned into a thread, and the paths the rest walked past
        - More selftest steps: releasing nothing, a resolver handing back either side, no
          count or status asked for, the value already there, and vectors of unequal length
        - The C is at 100% statement, branch, condition and subroutine coverage under
          Devel::XSCover on clang and gcc 14, with the unreachable marked

0.03    2026-10-15
        - Fix: pairs panicked on DEBUGGING perls 5.28 to 5.36

0.02    2026-10-14
        - last or next in a sub given to a method jumped out through the C
          and left perl corrupted; each sub now runs on a stack of its own
        - in each and diff, last stops the walk and next goes on
        - elsewhere last and next are the error perl gives outside a loop

0.01    2026-10-13
        - first version
