> Since Weld Extensions has adopted the EL expression resolver, it's fitting that it also provides an interpolator for strings containing EL expression.
> Provide an interpolator that resolves EL expressions and position parameters in strings. This feature was available in Seam 2 [1]. Since it's not provided yet in Seam 3, we see it showing up as a utility in various modules, including the International [2] and REST [3] modules. We should consolidate this to a single, authoritative source.
> It should probably be made an interface with implementations that process specific expression languages, such as EL. For instance, one implementation might interpret MVEL. Just an idea.
