[Haskell-cafe] How much of Haskell was possible 20 years ago?

[Maurí­cio]

Hi,

I like Haskell, and use it as my main
language. However, compiling a Haskell program
usually takes a lot of memory and CPU. So I was
curious, and would like to know from computer
scholars in this list: how much of Haskell would
be possible in machines with really low CPU and
memory? Which features would be feasible for a
compiler to implement, and for programmers to use?

Thanks,
Maurício
