Yeah, a bug in the emplace() version for classes, some missing 
`forward!args` in there (it works when emplacing a struct with 
identical ctor). E.g. 
https://github.com/dlang/druntime/blob/e2e304e1709b0b30ab65471a98023131f0e7620c/src/core/lifetime.d#L124-L128 if you want to fix it (std.conv.emplace is now an alias for core.lifetime.emplace in Phobos master).
