I don't think that Fusion will help me here, but I'll take a look at it.
IIUC Fusion won't help you here as much as Phoenix (the successor to Boost::LL) which already contains many of building blocks you'd need for your library.
Sure it will! In as much as Phoenix2 is built using Fusion, sure, I don't see why Fusion can't help here. We've seen how nifty it was for Spirit2 to be built on Fusion too. Composing the ET nodes, for example and doing the transforms on the composites was done quite elegantly thanks to Fusion. Think composites, think Fusion.
