Re: [Haskell-cafe] ghci: Difference in garbage collection etc. between REPL and function

ghci is in many ways like an endless (or at least until ":l"/":r") do-block. In particular, the handle remains in scope after you run your commands at the prompt, so it is not garbage collected. If you enclose it into its own do block, this introduces local scope and the handle goes out of scope and is garbage collected at the end.

I am not sure how the handle is relevant - I do not expect it to garbage collected before the close or rely on that, and my problem happens earlier already.
