Some people like sigils. Some people don't. In Perl 6 you don't have to use them (as much). 
my $x = 1; say $x;
my \y = 1; say y;

my @x = 1, 2; say @x;
my \y = @ = 1, 2; say y;

# also works with signatures
sub foo(\x) { say x }; foo(1);

However you can't use sigilless attributes 
class ThisExplodes
{
  has \.y; #doesnt work
  has \y;  #neiter does this
}

You can use this for example to distinguish normal variables from ones in closures, or lexicals from function arguments or whatever. Or maybe you event want to get rid of all sigils where possible.

The choice is yours.

Addendum
Sigilless variables do not create containers and are always immutable after initialization. They are therefore not a simple replacement with different visuals.

Edit: Fixed typo as hinted by NetWallah
