+    #                 match_expr
+    #   match_expr :: regex
     #                 identifier
+    #                 regex match_expr
+    #                 identifier match_expr
     #   identifier :: [-+=._a-zA-Z0-9]+
+    #   regex      :: '{{' any-regex '}}'
----------------
I'm not an EBNF expert, but the intent here was to describe that one can alternate `identifier` and `{{regex}}` inside what used to be just an identifier. This is to allow things like `abc{{regex1}}def{{regex2}}ghi`.
