According to:<br>

<a class="moz-txt-link-freetext" href="http://www.haskell.org/ghc/docs/6.6-latest/html/libraries/base/Data-Array.html">http://www.haskell.org/ghc/docs/6.6-latest/html/libraries/base/Data-Array.html</a><br>

<br>

it's not.&nbsp; It's just implemented differently by libraries:<br>

<br>

<blockquote type="cite">The Haskell 98 Report further specifies that if

any two associations in the list have the same index, the value at that

index is undefined (i.e. bottom). However in GHC's implementation, the

value at such an index is the value part of the last association with

that index in the list.

So, if I want multiple definitions diagnosed as an error, I'll have to

do it myself :(<br>
