The above isn't valid syntax because it is being parsed as an
assignment (not a method call) and (1,2) is not a valid
expression (RHS).

If you need something more complex, you can just assign with an
array:

self.foo = [1,2]

There is an RCR open to attempt to be able to do this type of
thing:

self.foo(*args) = value

which gets interpreted as self."foo="(*args,value).  This is
similar to the []= operator.
