> 1. Should assigning an arrayref to an array dereference?
No, an array in list context only flattens when it has the @ sigil, or
when it is explicitly flattened with the [] postcircumfix operator, or
the | prefix operator.

S03

No, because parens are just for grouping and controlling precedence.
They are not constructors.
Note that in this assignment,
my @foo = @bar;
@bar is in list context. The syntax is ARRAY = LIST; and not
ARRAY = ARRAY.
Assigning an array to an array seems kind of useless to me. Binding
probably makes a bit more sense:
my @foo := @bar;
That's ARRAY := ARRAY there, so the following should dwym:
my @foo := [ 1, 2, 3 ];
However, this does not work with pugs, so I don't know if I am wrong, or
pugs is wrong.
