The JSON parser optionally supports interpolation. The code calls it
"escape". Awkward, because it uses the same term for escape sequences
within strings. The latter usage is consistent with RFC 7159 "The
JavaScript Object Notation (JSON) Data Interchange Format" and ISO C.
Call the former "interpolation" instead.
