[boost] Re: [any] checked convertion to reference?

Currently, boost::any supports two kinds of conversion:

1. Unchecked conversion to pointer (NULL is returned if conversion is impossible) 2. Checked conversion to value type (exception is thrown if conversion is impossible)

I'd like to have another variant -- checked conversion to reference.

I'm very in favor of this. It has been proposed multiple times and Kevlin once told me he is going to extend any_cast this way, but it seems he is too busy. Stefan
