I don't know exactly what you mean by a reference pointer. If you mean a
pointer, there's no such thing as a pointer, although there is some way
to represent pointers in the NativeCall interface (which is properly
Rakudo) https://docs.perl6.org/language/traits#index-entry-CPointer.
There are no references either, as such. You can bind a variable to
another, but there's no special syntax for that.

Hi JJ,
This is what they look like in Perl 5:
sub GetOldRev ( $$$$$$ ) {
# Incomming:
my $Extension = $_[1];
my $WorkingDirectory = $_[2];
my $CallingFunction = $_[3];
# Outgoing. Note: these are reference pointers to
# the calling variables
# do not pass constants ("") to them
my $BaseTagPtr = \$_[0];
my $OldRevPtr = \$_[4]; $$OldRevPtr = -9999;
my $OldFileNamePtr = \$_[5]; $$OldFileNamePtr = "";
I will be happy if I never have to see a Reference Pointer ever again.
