I assume mine might come from the reflex cache, if it's not in main


Hmm - so I'm in try-reflex nix-shell and I'm trying to compile purescript with cabal.config set up to snapshot it normally uses with stack, and I'm getting this curious error:

Data/Conduit/Attoparsec.hs:108:19: error:
    * The constructor `TI.Text' should have 1 argument, but has been given 3
    * In the pattern: TI.Text arr1 off1 len1
      In an equation for `stripFromEnd':
          stripFromEnd (TI.Text arr1 off1 len1) (TI.Text _ _ len2)
            = TI.text arr1 off1 (len1 - len2)
      In the instance declaration for `AttoparsecInput TI.Text'

I'm yet to find version of Data.Text.Internal which exposes Text constructor with one argument... (it seems to use
