The Haskell 98 standard prelude is 39 kb big. Computers with less RAM than that were in use in the early 1980s. Since you're obviously an engineer by training, you may now ask why somebody would try to load an Haskell prelude in the early 1980s on a computer that isn't even capable of running a Haskell programme.
Anyway, I guess what I actually wanted to say got lost in the space between.
