I'm actually suprised, that your usage works.

puts('1', <<END)
2
END

That's how I'd have written it.
You can also use multiple

puts(<<FIRST, <<SECOND)
1
FIRST
2
SECOND

Or apply methods

puts(<<FIRST.upcase, <<SECOND.capitalize)
first
FIRST
second
SECOND
# (will print "FIRST" newline "Second")

Btw, no need for the 'q' method, puts can handle multiple arguments ;-)

Stefan
