Comment 4 for bug 698344

I suggested Henning push a branch with a Row expression since I
thought it'd be generally useful. Perhaps, when we fix the real
underlying bug, it won't be particularly necessary... but in general I
think it's not a bad thing to have expressions for builtin functions
available out-of-the-box.

So even though the addition of the Row expression isn't an acceptable
fix for the problem, I think it's a useful addition to Storm.
