Dave Mitchell writes: I spent September mainly working on two things. First, I made the stack grow macros EXTEND and MEXTEND more robust against count truncating and wrapping, especially on platforms where the sizes of ints and pointers differ. The initial impetus to do this was a bug reported against the repeat operator in list mode on a platform with 32-bit pointers but 64-bit ints; but new compiler warnings generated

Jonathan Worthington has requested an extension of $10,000 for his "Perl 6 Release Goals":http://news.perlfoundation.org/2015/04/grant-proposal-perl-6-release.html grant.

First, I continued working on re-jigging how scope entry and exit works I had already heavily reworked how subs are called, making a bare sub call: bc. sub f f use about 1/3 less instructions, branches etc. I've now made the more general loop and pp_enter context stuff use the new regime too

Dave Mitchell writes: I spent July mainly working on two things. First, I continued to work on the whole issue of how subroutines are invoked and returned from, and especially how the various perl stacks are manipulated during this time, i.e. all the PUSHBLOCK/PUSHSUB stuff. I also started extending the work to other context types, such as loops. I have mainly concentrated on removing unnecessary fields from the CXt_SUB context

It turns out that 6 stacks are involved, and there is lots of duplicated code, difficulties with stacks being doubly
