------------------------^
I think you dropped a '*':

*a = *[1,2] --> [a] = [*[1,2]] --> a = [1,2]

Is there a single good reference page that summarizes the rules for

     multiple assignment
     actual to formal argument assignment (for methods/lambdas)
     actual to formal argument assignment (for blocks)
     return expression to lhs assignment

I've seen it mentioned that the rules aren't quite identical for
all these scenarios.
