Changes

1.2.0.0 (2018-05-07)

  • Remove IsString (m Doc) instance (#16).

  • Export the beside function from both modules.

    • For non-Monadic pretty-printing this is identical to the Semigroup/Monoid <> combinator.

    • For Monadic pretty-printing this is the lifted version of <>.

  • No longer export <>. Use beside instead, or the Semigroup/Monoid instance (for non-Monadic).
