Is there a really good reason that the try statement (in C++, C#, JavaScript, etc.) and its friends catch and finally require a brace-enclosed block? What's wrong with this?

try
    DoSomething();
catch (x)
    LogError(x);

I know that the grammar doesn't allow it; I just wonder why. I suppose I could scour the newsgroups for the answer. Maybe I should ask on the proposed comp.std.csharp newsgroup.
