Hello All~
I have been reading the book "Haskell for real programmers" and am
presently on chapter 03.
There was a small program demonstrated by the author on "let". The
problem is that when I cut and paste authors code into eclipse, the
program works fine, where as when I write my own copy of the program I
am getting an error. I figured out that when I remove the function any
one function lend or bend, the file compiles and runs fine.
My question is why does the Haskell compiler complains, in the case 2
functions with the same signature and logic, even though their names are
different.
module Lending where
{-- snippet lend --}
lend amount balance = let reserve = 100
newBalance = balance - amount
in if balance < reserve
then Nothing
else Just newBalance
{-- /snippet lend --}
bend amount balance = let reserver = 100
newBalance=balance-amount
in if balance < reserver
then Nothing
else Just newBalance
Regards
