Your idea is:
  % [ $ pos ] format  -- ex. %$3l , %l
  Escapes: %% => %

Just for information, $ and pos are reversed in C sprintf.
  % [ pos $ ] format  -- ex. %3$l , %l
  Escapes: %% => %

IMHO, I like {} syntax as like as C# because the format strings are extensible.
  { pos [ : format ] } -- ex {3:l}, {3} (, and {l} could be also supported)
  Escapes: {{ => {, }} => }
