append package:turtle

Append chunks of bytes to append to a file The chunks do not need to be aligned to line boundaries
Stream lines of Text to append to a file
Acquire a Managed append-only Handle from a FilePath
An associative operation NOTE: This method is redundant and has the default implementation mappend = (<>) since base-4.11.0.0. Should it be implemented manually, since mappend is a synonym for (<>), it is expected that the two functions are defined the same way. In a future GHC release mappend will be removed from Monoid.
