ZPE production has currently stopped as I have decided to focus on my other projects a bit more at the moment. These projects currently include BalfBlog and my PhD. As a result ZPE production has currently been halted. This is a decision that has been made since ZPE is currently pretty stable and is already very impressive.
ZPE was never meant to be just another programming language, simply a little project I've been working on, and one that's given me a great insight into building a compiler and a language, as well as given me a lot of fun and something I can actually use to do some tasks.
The primary focus for me now is on the improvement of BalfBlog which is currently pretty stable too. BalfBlog needs new features added to it to make it more powerful and useful, but as I say it's pretty much done now anyway.
