How can I use Perl 5 modules from Perl 6?

Question

Is the a way to use Perl 5 modules from CPAN from Rakudo Perl 6?

For example, how can I use the venerable Perl 5 module, CGI, which hasn't been ported yet, in Perl 6.

Update:

And what this funky code from some early Perl 6 module:

use CGI:from<perl5>;

Is the :from<perl5> directive used to evoke some kind of a Perl 5 compatibility layer? Can't seem to find any documentation about it.

I understand CGI is just a example, but for modern web development you could look [Dancer for Perl6](http://ttjjss.wordpress.com/2012/01/06/state-of-dancer-on-perl-6) — w.k, Feb 07 '12 at 13:10

Like @w.k., I understand CGI is just an example, but, like them, I also want to mention a native Raku option for web dev, though in my case it's from the perspective of late 2019: [Cro](https://cro.services/). — raiph, Nov 30 '19 at 21:08

Use Inline::Perl5.

The following example shows how to use the CPAN hosted Perl 5 module Text::Unidecode ("the Unicode transliteration of last resort") in Raku.

First, install Inline::Perl5 if you don't already have it installed:

zef install Inline::Perl5

Now install the CPAN module if you don't already have it installed:

perl -MCPAN -e "install Text::Unidecode"

You can now use the installed Perl module by writing a use statement with an appended :from<Perl5> (with an uppercase P, not :from<perl5>) :

use Text::Unidecode:from<Perl5>;
say Text::Unidecode::unidecode 'Solidarność';

displays:

Solidarnosc

When I try to install Inline::Perl5 it says it can't find resources\libraries\p5helper.dll – Jim Balter Jun 21 '23 at 23:46

There is blizkost project that aims to use of perl5 code from Rakudo/Parrot. However it is AFAIK in quite early stage of development and probably not usable for real code.

@BradGilbert - yeah, thats why I put the warning there. However this is only project I know of that aims at using perl5 in parrot. – bvr Feb 08 '12 at 06:30
@bvr Parrot for Perl6 is also kind of dead. Rakudo FTF! (for the future) – user7610 Jan 14 '15 at 21:53
