Who would tell me, please, what is the simplest way to read a
string from a file?
Namely, what has one to set in place of `...' in the program
main = putStr (...)
to obtain instead of `...' a string contained in the file
foo.txt ?
Thank you in advance for the help.

I have a need to read large lists of numbers from a file and operate on
them. I tried the following:
read' =do s - readFile "temp"
print $ sum $ map (fst.head.readDec)(lines s)
But this is quite slow even for 1000 numbers.
Are there any other ways to do it faster? Will it help
