[Haskell-cafe] concatenate two Maybe String...

[Steven Shaw]

A quick and dirty answer might be:

  fmap (Data.Text.intercalate ".") resBDwords

I'd probably write it:

  Data.Text.intercalate "." <$> resBDwords

but you'd probably want to check your input has exactly two elements. You
could use pattern matching:

  f (Just [a, b]) = Just $ a <> "." <> b
  f _             = Nothing

Then (f resBDwords) gives you what you want I think and avoids head and
tail.
