Hi all,
this is assignment behaviour:

>> a,b = 1,2,3
=> [1, 2, 3]
>> a
=> 1
>> b
=> 2

and with a method:

>> def a_method
>> return 1, 2, 3
>> end
=> nil
>> a,b = a_method
=> [1, 2, 3]
>> a
=> 1
>> b
=> 2

If I want only one lvalue, is this:
>> a, = 1, 2, 3
=> [1, 2, 3]
>> a
=> 1
the only way to get it?

I would have liked for the return behaviour to be set on the right side,
to allow method invocation like:
>> puts a_method

to return:
1

instead of
1
2
3

Thanks all!

L-P
