To get the qw// parse you must put a space between the << and the quote. This is no hardship semantically, since qw// has always thrown away initial and trailing whitespace. Under one way of looking at it, it's just kind of a longest token rule, since << as a term only ever means qw, and the heredoc tokens are actually just long opening quotes: <<', <<", <<q/, etc. that have to match a trailing quote.
