The latest version of HeronFront has just been made and now compiles on GCC 3.4.1
As usual I am completely fried having pushed myself really hard to make this release. The latest changes are increased testing of Heron primitives, some IO functionality and compatibility with GCC 3.4.2. This release, version 0.5.9.6 can be downloaded here.
I have to brag though, the Heron parser engine (the YARD parser) is really fast! All modesty aside it is possibly the fastest recursive descent library available in C++. Anyway, it's all there and completely free if someone wants to use it. Even if Heron doesn't particularly float your boat, the code could come in handy for other things like designing a better language ;-)
