The following code (with comments) is confusing me.
Can someone give some explanation please?
Specifically the difference between
my @x = <a b>;
my $z = @x;
and
my $z = <a b>;
Gabor
use v6;
# < > creates an array here:
my @x = <a b>;
say @x.WHICH; # Array|140713422866208
say @x; # a b
say @x[0]; # a
@x.push('c');
say @x; # a b c
# we can assign that array to a scalar variable and it is still and array
my $y = @x;
say $y.WHICH; # Array|140498399577376
say $y[0]; # a
$y.push('d');
say $y; # a b c d
# but if we assign the same < > construct directly to a scalar
# then we get a Parcel
my $z = <a b>;
say $z.WHICH; # Parcel|(Str|a)(Str|b)
# $z.push('c'); # Cannot call push(Parcel: Str); none of these signatures
match: (Any:U \SELF: *@values, *%_)
# but if we wrap it in square brackets it creates an array
my $w = [<a b>];
say $w.WHICH; # Array|140272330353168
say $w[0]; # a
$w.push('c');
say $w; # a b c
