I am keen of collecting the computing polyglots. Honestly, they are bilingual - the main script with the small portion of the windows batch script as the second supporting language. And I like to call them hybrids.

I do it just for fun. And I know that some languages are hybridizing very well. Some of them are resistant to hybridization. And some of them that can be hybridized result to awful stuff. Such kind of polyglots I call chimeras.

Couple days ago I began thinking about how to embed a raku script within a batch file in the same way how it was done for perl with pl2bat.bat. I am not so familiar with raku and my first attempt doesn't look quite elegant. But it's working version and seems following the raku syntax and strictness.

I kindly ask fellows to help to improve it and make it better if it's possible.

@rem = q:to/use strict;/;
@echo off
raku -e "('no strict;' ~ (slurp q<%~f0>)).EVAL" %*
goto :EOF
use strict;
 
say "Hello! I am Raku.";
say @*ARGS;
[download]

Below are more suggestions from another people. The main problem with their versions that they are not pure hybrids and I classify them standing closer to chimeras because they use the raku syntax that is considered as the non existent external command and throws warnings by default. And it's a bit risky because it has non-zero probability to have such commands and execute them.

Both use the strange construction @@. What does it mean? I tried to google the answer but with no any success. In terms of the raku syntax I guess it looks like a nameless array of array. But I am not 100% sure.

The version using heredoc

@@; $_ = q:to/@@; goto :EOF/; # 2>nul
@@; raku "%~f0" %*
@@; goto :EOF
 
say "Hello! I am Raku.";
say @*ARGS;
[download]

The version using a multiline comments

@@; #`{ 2>nul
@echo off
raku "%~f0" %*
goto :EOF
}

say "Hello! I am Raku.";
say @*ARGS;
[download]

If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
