RFC: Template using PadWalker to access variables from inside task

Hi,

it would be possible with the PadWalker Module (https://metacpan.org/pod/PadWalker) to get the variables that the user declared inside a task. With this it would be possible to the something like this:

task "mytask", sub {
  my $x = 5;
  file "/tmp/foo.txt", content => template("mytemplate.tpl");
};

# the template
counter: <%=  $x %>

So it would be possible to access the variables from inside a task in the template that gets parsed in the task. With this the user doesn't need to pass the variables to the template function.

What do you think about this?

Review how task callbacks invoke template() and how template variables are currently passed. Evaluate the PadWalker proposal and its implications for accessing task-local variables. Done would require an agreed design and maintainer decision on whether templates should support this behavior without explicit variable passing.
