Re: [boost] [variant] Why boost::get<Base>(derived) not supported?

Hi there,

You can see the idea here: http://coliru.stacked-crooked.com/a/3e920faa604fa534

Is there any technical reason not having boost::get work like that?

I like the idea of polymorthic_get<>. Created a ticket https://svn.boost.org/trac/boost/ticket/9479 But I'm not sure that boost::get<> by default must work in that way. Won't there be ambiguity with `operator Base()`? And what if the user stores Base and Derived in boost::variant and want to chek that Base is stored in variant, not Derived? -- Best regards, Antony Polukhin
