That's easy.  Whether it's spelt with "+" or "|" or pretty much anything 
else, the operator version is clearer and cleaner.  "{**a, **b}" is a 
combination of operators and literal (display) syntax, and following 
Guido's reasoning that makes it inherently harder to interpret.  It's 
also ugly IMHO, but that's me.
