Is this how tagz.<< is supposed to work? It seems that << and #concat 
behave differently w.r.t. entity quoting.

require 'tagz'
include Tagz.globally

arrow = "&uarr;"
html = html_ {
   ___
   tagz << arrow
   ___
   tagz.concat arrow
   ___
   ___ arrow
}

puts html

__END__

Output:

<html>
&amp;uarr;
&uarr;

&uarr;
</html>
