[BUGFIXES]
* Ensure that anonymous methods can perform lexical captures from
outside scopes (RT132178)
* Ensure that subclasses without BUILD methods don't double invoke
that of their superclass
* Ensure a method's optree begins with OP_NEXTSTATE as debug tools
may rely on this (RT132413)
* Don't rely on Test::MemoryGrowth at test time, so tests can still
pass on non-Linux
0.24 (bad MANIFEST)
0.23 2020-04-21

* Add another new :repr type of autoselect, which chooses the most
appropriate type for the situation

avoids some refcounting issues that cause segfaults (RT132249)
0.16 2020-03-26
[CHANGES]
* Always generate the slots AV even with no slots because otherwise
METHSTART gets upset about no-slot subclasses

0.13 2020-03-15
[CHANGES]
* Use XS::Parse::Sublike for the bulk of the `method` parsing work
[BUGFIXES]
* Inline the code for Perl_package_version() because it isn't
exported API so not actually visible on non-ELF platforms
0.12 2020-03-10
[CHANGES]
* Minor adjustments to order of operations in method keyword parsing
to closer match core's parser
[BUGFIXES]

for derived subclasses better and avoid an infinite recusion loop
on double-subclassing.
