<pre>
I spent May mainly:
* heavily reworking perl's internal sprintf implementation.
I've now pushed a smoking branch containing about 100 commits which
fixes bugs, audits the code for possible integer overflows, makes the
code simpler and simpler to understand, and improves performance by
around 15%.
* Investigating short-string PVs. I've pushed a proof-of-concept branch
that allows short strings (< 16 bytes) to be stored directly in the
body of an SV. It also opens up a pathway to improve the COW
implementation, which I intend to work on at some point.
* helping to write and proofread the perldelta.pod file for the 5.26.0
release.
