[Haskell-cafe] Need help - my haskell code is over 50 times slower than equivalent perl implementation

Dear cafe,

I have created a reproducible app here -
https://github.com/ckkashyap/haskell-perf-repro

Essentially I am trying to open a number of files and printing out their
sized by reading them in and computing it's length.

I have the equivalent perl program also there. I'd appreciate it very much
if someone could take a look at my Haskell implementation and point out
what I am doing wrong. Since it's over 50 times slower than the perl code,
I assume I am doing something obviously incorrect.

Regards,
Kashyap
