warning(205): ../arden.xtext/src-gen/arden/xtext/parser/antlr/internal/InternalXText.g:2113:1: ANTLR could not analyze this decision in rule rulelogic_block; often this is because of recursive rule references visible from the left edge of alternatives.  ANTLR will re-analyze the decision with a fixed lookahead of k=1.  Consider using "options {k=1;}" for that decision and possibly adding a syntactic predicate.
