This extends quasis-quasitag-simple to allow richer QuasiTypeTags for use with quasis. Specifically, it allows quasi handlers to be name-spaced using ES5 idioms (my.namespace.foo`foo${bar}baz`) and it allows quasi handlers defined inside a loaded module to be used without being pulled into a member of the current module.
