I'm trying to understand Map type for possible use in another problem I'm
working on, but am stymied right off the bat.
==========Here's my source:
import Data.Map (Map)
import qualified Data.Map as Map
l1 = "abc"
l2 = [1,2,3]
==========Here's my error:
Prelude> :l maptest
[1 of 1] Compiling Main ( maptest.hs, interpreted )
Ok, modules loaded: Main.
*Main> l1
Loading package syb ... linking ... done.
Loading package array-0.2.0.0 ... linking ... done.
Loading package containers-0.2.0.0 ... linking ... done.
"abc"
*Main> l2
[1,2,3]
*Main> zip l1 l2
[('a',1),('b',2),('c',3)]
*Main> fromList $ zip l1 l2
<interactive>:1:0: Not in scope: `fromList'
*Main>
===========
Why isn't this working?
