[Pharo-project] Period at end of message pattern ?

Hi All, While filing in some sources form a friend into Redline Smalltalk the compiler generated an error on the following message pattern (method signature): initializeBetween: aPitcher and: aBatter events: aCollectionOfEvents. The error was the trailing period "." This is acceptable in Pharo but not in the Blue Book definition. I think it should be an error in Pharo as well. What do you think? Rgs, James.
