Also, it can be very handy to use it as an argument for a method call - so long as you know what you're doing. As I keep saying, avoid cargo cult programming - if you make sure you know what your code means, you'll be okay. >>> You *could* compare it to macroes, C# does not support macroes, and I >>> am glad it does not. >>> Too often macroes led to code that was not so obvious at all... >> True - but this one rarely comes up.

I've very rarely seen this to be a problem on the newsgroups. Occasionally, yes - but there are much more frequent issues, and it's easy enough to point out that it's a bad idea.
