I have Fedora 31 and Readline does not seem to be working for me in the
raku REPL as well.
But see below!

Hi All,
Fedora31

I have the same setup on both computers. On
my shop computer, in REPL, the arrow keys
do not read correctly:

How do I get my arrow back in REPL on mu
shop computer?
Many thanks,

Seems to me I have see the last expression returned even without
the {...}. Maybe I am misremembering.

Hi All,
What is the syntax for returning two variable from a sub?
> sub x(--> Int, UInt) { return(-2,4) };
===SORRY!=== Error while compiling:
Malformed return value (return constraints only allowed at the end of
the signature)
--> sub x(--> Int⏏, UInt) { return(-2,4) };
Many thanks,

Not sure it is *the* reason, but the return type is part of the signature of a
sub x( --> Hash) { my %h = A => 'a' }
1) '-->' in the signature is the best way to provide information to the
compiler about what the subroutine should return
2) 'returns' in the declaration (not the part in the block) used to be
used, but for some arcane reason that I never really
" 'while' ...will stop when it encounters a false line--typically an
empty line or '0' ".
Wasn't that the point of p5's defined
while ( defined(my $line = <> ) ) {
or (previously lexified '$val'):
print "$val\n" while defined($val = pop(@ary));

Good answers, all. Thanks to everyone for contributing.
For anyone who wants a golfed "cat" replacement, command line
arguments can give you shorter code:
mydir$ perl6 -e '.say for lines' ab_cd.txt
a
b
c
d
mydir$ perl6 -ne '.say' ab_cd.txt
a
b
c
d
mydir$ # below two single quotes as empty
New addition to my hash keeper:
"returns" hash on a sub declaration:
Note: "Associative" will return a hash or a map or even a pair
> sub x() returns Associative { my %h= A=>"a"; return %h}
> x
{A => a}

Hi Tom,
Interesting. I have been showing both in my keepers.
I currently use "returns "
