Apparently other people thought this was silly as well and they gave us var - the compiler infers the type based on the type being created or returned by a method. OK, so they didn't give it to us for that reason, it was needed for anonymous types. But it's still a welcome addition.

Bingo, that's the one I was thinking of. Thanks to both you and Gregory for straightening me out. I am back to immersion study of C# and .NET, and boy do I need it ;-) After 9 months back working with VFP and SQL Server it seems like half of what I knew, such as it was, has flown away. It's really true what they say -- you have to use it. Book learning doesn't really burn in, at least not for me.

Definitely count me among those who thought commands of the form "StringBuilder sb = new StringBuilder()" seemed silly.
