+## Strict binding parser
+
+The default implementation of the binding parser uses a regular expression, due to its better
+performance. However, since it uses a white-list of allowed characters, some characters won't be
+accepted as valid within a binding expression.
+
+There's a strict binding parser implementation, extracted in a separate mixin, which uses a
+state-machine instead of a regular expression. This implementation is able to handle all possible
+cases, although it's slightly less performant.
+
+Example: { .caption }
