IMO it is better not to do that since E4X would allow to write the above as:
var userName = request.getParameter("user-name");
OUT(I see your name is {userName}!
)
if(userName != "Bob") {
OUT(Say "Hi" to Bob if you see him.
)
} else {
OUT(Bob, it is nice to see you again.
)
}
where OUT does proper job of appending string to response.
