malcolm: Thu Jan 11 19:22:02 CET 2001 Update of /usr/src/master/nhc/src/prelude/IOExtras In directory hinken:/tmp/cvs-serv21043/IOExtras Modified Files: FreezeIOArray.hs Makefile NewIOArray.hs ReadIOArray.hs WriteIOArray.hs Removed Files: _E.hs Log Message: Improve the performance of Arrays. Re-implement two key routines to use encapsulated unsafeIO: 'array' to build a new array '//' to modify an array (i.e. a copy) This dramatically improves speed and space behaviour - in the latter case it converts a quadratic algorithm to linear.

It turns out that IO (\world-> something) gives nasty traces, but IO (const (something)) gives nice traces. The underlying reason is that the "trusting" mechanism for lambda abstractions is wrong, but this is a workaround until "trusting" is fixed.
