this means a larger code size.
Why?? In both cases I'd ultimately expect to see a top-level machine- code label for a literal string, and a reference to that label in the compiled code. I see no reason for increased code size, or increased bytes-allocated.
Sorry, I meant a larger size of the core. Presumably the compiler needs to use more memory to store a larger syntax tree. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8472#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
