Does that mean the context where the wantarray is, or where the function call is?

Where the function call is.

If it's where the function is called as a hash value

blah() is not called "as a hash value". It is called while building a list (which eventually will be assigned to a hash.) For example:

%hash = (a => 'b', 'c', d => split(//, 'ef'));

results in

$hash{'a'} = 'b'
$hash{'c'} = 'd'
$hash{'e'} = 'f'

It's useful to think of the () as an operator creating an anonymous list.

couldn't you're example just as easily be (1, $a), instead of (1, @a)?

Yes, a scalar can be be provided when an a list is expected. However, I used @a because an array behaves differently in scalar and list contexts. (It returns the number of elements in the former, and the list of elements in the latter.)
