* Fix Trac #4396, by localising pattern binders in the desugarer
See Note [Localise pattern binders]
M ./compiler/deSugar/DsUtils.lhs -5 +43
}}}
Also I improved Lint to catch the error earlier:
{{{
Fri Oct 22 08:24:05 BST 2010 [email protected]
* Lint should check for duplicate top-level bindings with same qualified
name
This would have produced a more civilised error for Trac #4396
M ./compiler/coreSyn/CoreLint.lhs -11 +29
}}}
