Indeed, when I reported this business about the syntax coloring of Curl to Wolfram tech support, they responded quickly to point out it indicates shadowing (hence -- they did not explicitly say this -- it's not a bug). The trouble is, before you load the VectorAnalysis package, Curl seems to have no meaning other than as a symbol: ?Curl System`Curl And if you search for Curl in the Documentation Center, you seem to get no item related to that name in the System context. This is an annoyance, yet I don't see a wholly satisfactory resolution to it. Having Curl available in the System context means you can define your own definition for it.
