Comment #2 on issue 3462 by guillermopolito: [Failing Test] SHParserST80Test.testNumbers http://code.google.com/p/pharo/issues/detail?id=3462 The failure is in here: s := 'x 1--1'. types := self tokenTypesIn: s. tokens := self tokensIn: s. self assert: types = #(patternUnary number binary #- number ). self assert: tokens = #('x' '1' '-' '-' '1'). Because it's recognizing the tokens: #('x' '1' '--' '1') whose types are #(#patternUnary #number #incompleteBinary #number)
