You may want to try Data.PackedString which comes with GHC (if you are
using GHC that is).

Because that's the way it was done in Miranda, almost 20 years ago.
OK, to be fair, it does make string-to-string operations a bit more
convenient. Apart from undergraduate homewo
Hi, can someone tell me why Haskell strings are linked lists? I have
had some problems with Haskell strings:
1. Today I spend a few hours trying to track down a memory leak. It
turns out I just didn't realize how much space a string takes up.
On my machine "replicate 500 'a'" will u

Yes, I am. I could probably make them myself, but if you
are willing to do so, I will let my 200 MHz machine do
something else... :)
Best wishes and big thanks anyway,

Hi,
If I compile and run the code below, the file "foo" contains 10 lines
of output (as I would expect), but the file "bar" contains just 9 -
the final line is missing. If I add a "join", as in the comment, then
all 10 lines appear.
I don't understand why, completely - my best guess is that it'
