I went to [bart.gooogle.com] and asked it: "How do you write lambda functions in Raku?"

Here's how it responded:

To write lambda functions in Raku, you can use the following syntax:

Code snippet

Xliff

raku -Ilib -e 'use experimental :rakuast; use MONKEY-SEE-NO-EVAL; my $ast = RakuAST::Statement::Need.new( module-names => [ RakuAST::Name.from-identifier(RakuAST::Name.from-identifier("GLib::Raw::Definitions")) ] ); EVAL $ast; import ::("GLib::Raw::Definitions"); glib.say'

This is the exact testing data. It's execution ready if you clone p6-GLib, you should only need to change into the project directory and run the above. Otherwise you will have to create a .rakumod file with a constant declaration and replace the glib in the above script with the name of that constant.

So I needed to access the symbol table of one of my modules, recently. After a few hours on the web (and after wracking my brain for a bit) I came up with the following:

sub getSymbolTable (\T, $cu-name) is export {
  return Nil unless $cu-name;

  my $nodes = $cu-name.split('::').Array;
  my $fn    = $nodes.shift;
 my $st = T.WHO{$fn};

Does anyone see a problem with this? If so, I will submit the PR.

I wrote up a quick and dirty editor as a test case for some my GTK4 work.

Heres a sample screenie:

And here's what the code looks like:

use v6.c;

Here's something I wrote for guifa a couple of days ago. I am thinking of turning it into a simple Rakuish event loop for my projects.

Is this a fairly decent implementation, or is this just NIH for cron?

Please share your thoughts.

my %suppliers;

Have I told you how wonderful I think Raku is?

Well I don't have enough words to do that.

However even the best languages have thier faults, and one of Raku's the following:

sub a ( :name(:named(:$names)) ) { ... }

So I was looking through what I have written for $dayJob, as far as my work with a Cro-based application server is concerned.

It occurred to me that we might be able to clean up what is already a fairly clean Cro dispatch handler.

Consider this example:

  route {
    get ->                { ... }
    get -> '2'            { ... }
