See RBParserTest>>#testBinarySelectors It's based on the draft ANSI Smalltalk-80 standard. You integrated it. It tests the RBParser's parsing of binary method definitions and message sends of all binary selectors from 1 char upto 3 chars. (The Blue Book is more restrictive than ANSI, limiting them to 2 chars max IIRC.)
I wrote the test because of issues I had with the OldCompiler's handling of selectors containing "|" and issues on other platforms like GemStone, so the behavior I need and think is correct won't get broken without warning.
