String Interpolation with Records

[senlin-stars]

Is it possible to do something along the lines of format <template> <data>

record: {
   iso: "fr"
   continent: "europe"
}

output: "%(iso)s-%(continent)s" % record // => "fr-europe"

I know that this flavour of string interpolation "\(iso)-\(continent)" is possible. However, record and output both are stand-ins for data so I cannot make use of cue-level string interpolation.
