Hi Russ,
You probably have the monomorphism restriction turned of, so you don't get
an error message. If you add a type, it will work fine. Like this:
Prelude> read "123"
*** Exception: Prelude.read: no parse
Prelude> read "123" :: Int
123
Prelude>

Hi,
I'm having a problem with the read function. I thought it took a string and converted it into a value (if there is a conversion). But it doesn't seem to work for me on GHCi
Prelude> read "123" *** Exception: Prelude.read: no parse Prelude> read (show 123) *** Exception: Prelude.read: no parse
There must be something trivial that I'm missing.
Thanks.
