Re: [FreeMarker-user] Can I make user-defined directives part of a hash?

[Newman, J. W <new...@d3...>]

I think something like 

[#assign varName] [@foo.bar param=value /][/#assign]
${vars["foo"][varName]}

might be what you are after.

Certainly, however that change should be scoped lexically (right?), so it's certainly not trivial to implement. But yeah, I know of situations that needs multiple data-models...
