Subject: [PATCH] feat(parser): add pipe token to grammar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add "|" token to @tokens section to support pipe operator. This is the
first step in implementing Unix-style pipe expressions for chaining
function calls.
