Re: [myhdl-list] Conversion error: Type mismatch with earlier assignment

Thanks for pointing this out. I guess the error code could be extended to 
include "Did you forget [:]?" Assuming this error code only applies to 
exactly this case (it probably does).
I experimented a bit and found out I was wandering astray somewhat. 
Using an intbv assignment without the [:] would bind the name to another 
object. Using [:] avoids this and updates the actual intbv object itself.
Now I still am struggling a bit with the idea of having to use [:] on the 
LHS of the assignment especially as you don't have to when using an 
Augmented Assign (e.g. +=). 
I now also understand/recall avoiding this error by converting the 
arguments into integers in my code.
