Re: [Haskell-cafe] Strictness in do block

What I want to know is the generic way to force an entire String (or other list, perhaps from hGetContents) to be evaluated (read into RAM, I guess) so the underlying file can be closed.... and do it right now. What I have done in the past is to take the length of the string, and test the length in some way - although I guess you could call seq on

Hi, the length. Of course, the length tests technically doesn't evaluate the character positions (just the spine of the list), but it always works in practice. Thanks Neil
