an idea: @context in coercion rules ?

Hi,

an idea that came to me while reading the JSON-LD syntax document is one
could put a @context inside a coercion rule,
in order to change the meaning of a property depending on where it appears.

For example,

{
  "@context": {
    "name": "http://xmlns.com/foaf/0.1/name",
    "homepage": {
      "@id": "http://xmlns.com/foaf/0.1/homepage",
      "@type": "@id",
      "@context": {
        "name": "http://purl.org/dc/terms/title"
      }
    }
  },
  "name": "Manu Sporny",
  "homepage": {
       "@id": "http://manu.sporny.org/",
       "name": "Manu's homepage"
  }
}

would give the following triples

_:t0 <http://xmlns.com/foaf/0.1/name> "Manu Sporny" .
_:t0 <http://xmlns.com/foaf/0.1/homepage> <http://manu.sporny.org/> .
<http://manu.sporny.org/> <http://purl.org/dc/terms/title> "Manu's
homepage" .

where property name means foaf:name or dc:title depending on where it
appears.

Has this been discussed in the community group? Does this look like a valid
use case?
