Hello, here are my votes on Simon Marlow's questions.
Issue 1: should the maximum heap size be unbounded by default? Currently the maximum heap size is bounded at 64M. [..] 1. remove the default limit altogether 2. raise the default limit 3. no change
Put the default to 30M.
Issue 2: Should -M be renamed to -H, and -H renamed to something else? The argument for this change is that GHC's -M option is closer to the traditional meaning of -H.
Yes.
Issue 3: (suggestion from Julian S.) Perhaps there should be two options to specify "optimise for memory use" or "optimise for performance", which have the effect of setting the defaults for various GC options to appropriate values. [..]
All right. But let the meaning of -O remain as it was. ----------------- Serge Mechveliani mechvel@botik.ru

That seems to be on the low side. Obviously people's opinions will always differ. Why not introduce environment variables to allow for people to set their own defauls settings?

I like the enviornment variable option, I would very much like to have part of my log-in sequence parse the output of 'free' or some other real memory reporting tool and set the limits as appropriate for the system I happen to be on.
