If for some reason you absolutely need to avoid parentheses (mostly as a thought exercise, I guess), you'd have to have a flipped version of intercalate:

Or a version of ($) that associates differently.

infixl 0 $$

f $$ x = f x

*Main Data.ByteString> :t \x y z -> intercalate $$ intercalate x y $ $ z \x y z -> intercalate $$ intercalate x y $$ z :: ByteString -> [ByteString] -> [ByteString] -> ByteString
