Yeah, but there is a twist if you list targetnames. But that depends on
the situation. 

module Mrtg =

(* d[t] :v *)

let dels (s:string) = del s s

let record (targetname:string) = [ label targetname . [ key /[a-z]+/ .
dels "[" . dels targetname . dels "]:" . store /[a-z]+/ ] ]

let cfg = record "foo" | record "bar"

test cfg get "somedirective[foo]:somevalue" = { "foo" { "somedirective"
= "somevalue" }}
