Hello, I have released a new version of Seed7: seed7_05_20120506.tgz In the Seed7 programming language new statements and operators can be declared easily. Types are first class objects and therefore templates/generics need no special syntax. Object orientation is

Compiler positions available for week ending May 6

This is a digest of ``help wanted'' and ``position available'' messages received at comp.compilers during the preceding week. Messages must advertise a position having something to do with compilers and must also conform to the guidelines periodically posted in misc.jobs.offered.
