In a previous article, I wrote about how it was difficult to produce a 2D list in Copper due to the ownership dilemma. The solution at the time was to write a singly-linked list in Copper. It turns out, there is a better approach, one that will also allow us to create any multi-dimensional list.

foreign.run(anytime)
Up to this point, the foreign function system did not allow using callbacks via Engine::runFunctionObject() until after Engine::execute() or Engine::run() (which calls Engine::execute()) had completed. My recent update changes that and makes recursive execution of opcodes easier.
Progress Report #7
Back at it again, this time I’ve made some important bug fixes that have laid hidden since branch Cheetah. Uh oh. Sometimes a bug can be simply reference counting too much, in which case, we call it a memory leak. The major issue, however, was a parsing bug that duplicated variable address names. Hard to believe I missed something as important as that, but it required a certain state of the parser, so I don’t feel quite as bad about missing it. In any case, those are done.
Progress Report #6
A number of things have changed with regards to the internals. A great deal of time has been spent trying to optimize the engine, resulting in some interesting discoveries.
