How to programatically access a Light's Shadow Bias?

In Unity 2, each light object had a ShadowConstantBias and a ShadowObjectSizeBias. Now, in Unity 3, each light just has a Bias.

I need to set this bias from a script, but can't figure out how to do so. Inspecting UnityEngine.dll didn't turn up anything useful.

To what internal Unity var is each light's Bias gui slider linked?

Whoops, that was an oversight in Unity 3.0. Will be fixed in next release (which probably will be called "3.2")

Not everything is exposed to scripting. If there's no property listed in the docs, that means it's not possible.
