set metadata: "/" in field?

I'd like to set metadata with a slash e. g.

arnold/AA_samples=10.

How on earth can I input a / in a metadata field?!

/ is a reserved character in Lua, which is the language the Set Metadata Fuse is written in. It should be possible to add some code to the Fuse to parse out a slash, though. I don't have the time right now to look into it. Ask your question over at Steakunderwater.com. One of the others who hang out there may have the time to fix it. It's even possible that someone already has a modified Fuse that they'd be willing to share; it's been known to happen.
