If you want to resolve it just do

     const label_size = CalcTextSize(...);

but as others have mentioned make sure it is the right type 
(although if they are functionally identical it won't matter).

My immediate thought is 'is that the same ImVec2?' Do you have 
two definitions of ImVec2 laying about?

What's the output of this code, if you insert it somewhere in the 
above?

import std.traits;

pragma(msg, fqn!ImVec2);
pragma(msg, fqn!(typeof(CalcTextSize(label.ptr, null,
 true))));

Darnit. I just googled the template and got a result talking 
about fqn!T. So yeah - this code:

pragma(msg, fullyQualifiedName!ImVec2);
pragma(msg, fullyQualifiedName!(typeof(CalcTextSize(label.ptr,

This is exactly the cause. Output is follows:

     internal.ImVec2
     types.ImVec2

I'm leveraging types as I try to do my own port of the lib so 
CalcTextSize is returning an instance of ImVec2 as defined types 
and I'm trying to assign to one I have declared in internal.

Thanks.

I don't know why you have two different ImVec2s, but you may have 
good reasons to. If they need to be separate, you'll need to 
write a conversion function between the two for the cases where 
you have one and want the other. This could be the constructor or 
opAssign, or a standalone function if you want to be more 
explicit about it.

I'd argue that error message could be improved upon, btw.
