We have a data type equivalent to a recursive variant that can hold a 
few scalar types or a vector of such types.

My colleague proposes that we build a template function that will accept 
a free function or class method (that is, any callable whose signature 
we can infer) plus a vector of the variant type. For each formal 
parameter type in the callable's signature, this function would ensure 
that the vector is long enough to fill it, and then that the runtime 
type of the appropriate vector entry is compatible with the static type 
of the parameter. Finally it would call the callable, filling the formal 
parameters from the variant vector.

I strongly suspect that this function already exists in Boost. I simply 
don't know which library to research. (OvermindDL1?)
