 Ausaf and Urban cleverly defined an auxiliary function called $\flex$,
 defined as
-\[
-\flex \; r \; f \; [] \; v \; = \; f\; v
-\flex \; r \; f \; c :: s \; v =  \flex r \; \lambda v. \, f (\inj \; r\; c\; v)\; s \; v

 which accumulates the characters that needs to be injected back, 
 and does the injection in a stack-like manner (last taken derivative first injected).
 $\flex$ is connected to the $\lexer$:
