In fact there are two operators, namely "|" and ">".  And expr "|" ">" is
not valid Ruby syntax.

You can do things like

puts <<EOM
This
is
a
multi
line
String
that
can
get
quite
long
and
even
contain
expressions
like
#{1+2}.
EOM

puts %{
This
is
double
quote
text.
\tsee?
#{1+2}
}

%Q{} works also, as well as "".

puts %q{
This
is
single
quote
text.
\tsee?
#{1+2}
}

....
