Hi I agree that automatic code migration can solve this issue in large parts. The Python folks have done this to mitigate the transition from version 2 to version 3 [1]. On Thu, Aug 30, 2012 at 03:03:05PM +0200, Alexander Kjeldaas wrote:

I don't think regular expressions are powerful enough. This example does not match on hiding multiple names, for instance. But writing proper 'HsModule -> HsModule' functions should be doable. And when each release comes with a bunch of such functions, packages could be automatically migrated. Greetings Alex [1] http://docs.python.org/library/2to3.html
