On November 21st, we met at the office of Ikos Consulting in Levallois-Perret. In the presence of the creators, the designers, and the users of the language, we agreed about future enhancement processes and started the process to precisely define the next version of the HLL language definition.
The next steps will be to concretely agree about the precise definition of the next version of the HLL language, the features to be added having already been decided. We also have a few details to sort out about the legal structure of the HLL Forum.
Prover would like to thank all participants for their proposals and comments about how to organize the HLL Forum in the future.
Prover is also particularly grateful to IKOS Consulting who welcomed us in the best conditions to a serene and efficient day.
