VectorAnalysis`Curl is only one such instance of this phenomenon. Another, of which you may be aware, is Combinatorica`Star. My guess is that the effort here is being devoted to just moving the functionality of such packages into the kernel, although in some cases with a whole different design (e.g., with the new kernel function Graph, etc.) rather than trying to patch up messages, etc. Murray On 12/14/2010 6:55 AM, JUN wrote: > Hi, > there is a new shadowing conflict in version 8 that affects the Curl > operator from the VectorAnalysis package (heavily used in my > electrodynamics lecture): because of an existing System`Curl, the > former Curl is now highlighted as a shadowing conflict (although it > still works, fortunately). > > I didn't find any replies to an earlier post where this issue was > raised: > http://forums.wolfram.com/mathgroup/archive/2009/Jan/msg00039.html > > So right now I am resorting to this preamble to avoid the annoying and > confusing red highlighting of this ubiquitous operator: > > SetOptions[$FrontEnd, > First[Options[$FrontEnd, > "AutoStyleOptions"]] /.
