#14309: Expand comment in hPutStrLn -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: task | Status: new Priority: normal | Milestone: 8.4.1 Component: Core | Version: 8.2.1 Libraries | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Documentation Unknown/Multiple | bug Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- A comment on `hPutStrLn` reads

An optimisation: we treat `hPutStrLn` specially, to avoid the overhead of a single `putChar '\n'`, which is quite high now that we have to encode eagerly.

This should reference some code or comment that explains why the cost is high, why we have to encode eagerly, what it even ''means'' to encode eagerly, etc. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14309 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
