This is a bug, but I've finally fixed it! Yes! You can wait for the next

Normally this wouldn't work as expected, since <TMPL_VAR NORMAL>'s
value outside the loop is not available inside the loop.
+The global_vars option also allows you to access the values of an
+enclosing loop within an inner loop. For example, in this loop the
+inner loop will have access to the value of OUTER_VAR in the correct
+iteration:

+ <TMPL_LOOP OUTER_LOOP>
+ OUTER: <TMPL_VAR OUTER_VAR>
+ <TMPL_LOOP INNER_LOOP>
+ INNER: <TMPL_VAR INNER_VAR>
