Hello all,
I'm trying to create a recursive variant over an MPL
vector.<http://?shva=1#drafts/128ba01f42cb2169>

attached is the code.

I'm trying to add a templated function isType, which will return true if the
type stored in variant is the type queried for or false otherwise.

This doesn't work for recursive types.

In the example, I expect the program outputs "Map Type" because the type
stored in the variant is a map. but it says the type is not map.

The problem is mpl::contains returns false for map type. (The type stored in
mpl vector is boost::recursive_wrapper< map ... >, where as, I'm querying
for map...). what is the way forward from here.

Thanks,
Surya.
