Re^7: Binary to decimal conversion

Because print takes a LIST and hence provides a list context to reverse which triggers the list context behavior from the latter (and a 1 element list reversed is indistinguishable from the original 1 element list for obvious reasons). Stick a scalar in there after the print, and/or store the reverse into a scalar temporary variable, and you'll see the behavior you're expecting.

The cake is a lie.

Said code (and then some): `$\ = "\n"; print(my @a = reverse('hello')); # hello (order or scalars reversed) print(my $s = reverse('hello')); # olleh (order of chars reversed) print(reverse('hello')); # hello (order or scalars reversed) print(scalar(reverse('hello'))); # olleh (order of chars reversed) sub f(@) { return @_; } sub g($) { return @_; } print(f(reverse('hello')); # hello (order or scalars reversed) print(g(reverse('hello'))); # olleh (order of chars reversed)` [download]	[reply] [d/l]

$\ = "\n";

print(my @a = reverse('hello'));  # hello (order or scalars reversed)
print(my $s = reverse('hello'));  # olleh (order of chars reversed)

print(reverse('hello'));          # hello (order or scalars reversed)
print(scalar(reverse('hello')));  # olleh (order of chars reversed)

sub f(@) { return @_; }
sub g($) { return @_; }

print(f(reverse('hello'));        # hello (order or scalars reversed)
print(g(reverse('hello')));       # olleh (order of chars reversed)
