Raku++ 5.0.0-g312cde8e prints exactly what Rakudo 2026.08 prints

This is valid Raku: Rakudo 2026.08, the reference compiler, runs it without complaint, and the two outputs match character for character.

The program

The first lines compute $value. The last four lines are the same in every program: they print what kind of thing $value is, how it looks as code, as a string, and as true or false.

sub bind(:$x!) { $x }
my $value = bind(x => 42);

sub safe-str($v) {
    my $s = try $v.Str;
    $s.defined ?? $s !! '<undefined>'
}

say "TYPE\t" ~ $value.^name;
say "RAKU\t" ~ $value.raku;
say "STR\t" ~ safe-str($value);
say "BOOL\t" ~ $value.Bool;

Run executes the program in your browser, with the Raku++ build this site ships. Edit it and try variations.
