I've been thinking about stuff like this as well.
It happens to me as well that I spend minutes on finding an error till I
notice that I've misspelled a word.. but this has been while programming
PHP. In haskell this kind of error tends to take much less time IMHO.
There is a "friendlier" shell (don't remember it's name) which takes
Change color if the word is known.. In case of ghci the commandline
could switch color to green before pressing enter to indicate there are
no errors left..
