Almost. Grep operates over Shell Line. Line is just a newtype over Text. I still don't know if this is telling me "don't do that".

Dear list

On the Turtle library, the grep function got the following signature

grep :: Pattern a -> Shell Line -> Shell Line

For it to filter output of the `ls :: FilePath -> Shell FilePath` I got to fmap and transform via de Turtle.Format or Turtle.Line modules. Is this an indicator I shouldn't be doing this? Is the library telling me to use `find`? or is just accidental?
