Hi Todd,
Do you not have a working Raku/Perl6 REPL install? If you do, when
copying (single-quoted) code out of https://docs.raku.org , you could
try the following strategy of pasting into the REPL first, before
pasting code at the command line:
> my $repl_code = Q[my $map = Map.new('a', 1, 'b', 2); say $map{'a'}; say $map{
> 'a', 'b' };]
my $map = Map.new('a', 1, 'b', 2); say $map{'a'}; say $map{ 'a', 'b' };
> my $dashE_code = $repl_code.subst("\'", "\"", :g);
my $map = Map.new("a", 1, "b", 2); say $map{"a"}; say $map{ "a", "b" };
> say $dashE_code
my $map = Map.new("a", 1, "b", 2); say $map{"a"}; say $map{ "a", "b" };

(Yes, capital "E" does nothing as a Raku/Perl6 command line flag, I
just wrote camelCase "dashE" to distinguish the letter "e").
HTH, Bill.
