fallback(this, name, args...)

Dynamic metadata.

This fallback methods dispatch to getting or setting the corresponding metadata on the receving element, depending on the number of given arguments.

For instance, elt: foobar(42) will dispatch to elt: metadata("foobar", 42), provided that the elt element does not have a foobar method. Conversely, elt: foobar() will dispatch to elt: inheritedMetadata("foobar").

A Golo element have thus a behaviour similar to a DynamicObject with respect to its metadata.
