Yeah, but how many of them are involved in compiler development? I think this is in poor taste. I can't imagine that they're not trying to capitalize on flex's fame.
Alan Kay's Flex quickly became Smalltalk while Flex (the lexer) spent the last 30 years doing its thing under that name. It might not be deliberate but it's definitely confusing and they definitely should have realized it would clash within the compiler development namespace. It's like making an HTML parser and calling it Chrome.
