Actually the syntax is correct. However, one advantage of heredoc is 
that you can use quotes freely, e.g. this does *not* work (unless you 
escape the double quotes):

%{?scl:scl enable %{scl} "}
# this is a shell
command "1"
command "2"
...
%{?scl:"}


while this is perfectly OK:


%{?scl:scl enable %scl - << \EOF}
# this is a shell
command "1"
command "2"
...
%{?scl:EOF}


In other words, heredoc makes the conversion from regular .spec to SCL 
.spec a bit easier in some cases.
