Release 0.11 Incorporates a fix from sjamaan (Peter Bex) for CHICKEN 5.0.2 and later. His original comment: > In older CHICKENs, keywords could be bound like regular symbols, which was a bit of a strange behaviour. In 5.0.2 and later this no longer works, so we'll need to either quote the symbols using pipe characters or disable the keyword style reader. The latter is best for portable code as it requires no actual changes to be made to the upstream code. > So the patch simply disables keyword style, so that identifiers like :comparator: are accepted
