I've tried loading it in both Pharo 5 and 6 with the same results when selecting the Pillar tab in GT Inspector: PPContext(Object)>>doesNotUnderstand: #identifier PPMemoizingSea(PPSea)>>check: PPMemoizingSea>>parseOn: PPActionParser>>parseOn: PPDelegateParser>>parseOn: PPChoiceParser>>parseOn: PPPossessiveRepeatingParser>>parseOn: GTPillarParser(PPDelegateParser)>>parseOn: GTPillarParser(PPParser)>>parseWithContext: GTPillarParser(PPParser)>>parse:withContext: GTPillarParser(PPParser)>>parse: GTPillarHighlighterTextDecorator>>parse:onError: GLMHighlighterTextParserStyler>>privateStyle: [ self privateStyle: text. view ifNotNil: [ view stylerStyledInBackground: text ] ] in [ backgroundProcess := [ self privateStyle: text. view ifNotNil: [ view stylerStyledInBackground: text ] ] forkAt: Processor userBackgroundPriority ] in GLMHighlighterTextParserStyler(SHTextStyler)>>styleInBackgroundProcess: in Block: [ self privateStyle: text....
