Trying to understand how compilation works

cache.p6

use nqp;

role GenericCache {
    has $.precomp-repo;
    method pod (Str :$name) { ... };
    method list-files (--> List ) { ... }
}

class Cache does GenericCache {
    submethod BUILD(Str :$dir) {
        $!precomp-repo = CompUnit::PrecompilationRepository::Default.new(
            :store(CompUnit::PrecompilationStore::File.new(:prefix($dir.IO))),
        );
    }

    method pod (Str :$pod-file-path ) {
        my $handle = $!precomp-repo.try-load(
            CompUnit::PrecompilationDependency::File.new(
                :src($pod-file-path),
                :id(CompUnit::PrecompilationId.new-from-string($pod-file-path)),
                :spec(CompUnit::DependencySpecification.new(:short-name($pod-file-path))),
            ),
        );
        my $pod = nqp::atkey($handle.unit, '$=pod');

    }

    method list-files () {return ();}
}

constant DIR="doc/";
my $cache = Cache.new(:dir(DIR~".precomp"));

# first time I execute this, that file will be compiled
$cache.pod(:pod-file-path(DIR~"somepod.pod6"));

# Q1: what happens if I call it? It's compiled again?
say $cache.pod(:pod-file-path(DIR~"somepod.pod6"));

# Q2: The second time I run this script, if I call that method again, will it use the
# already compiled version? or will recompile de pod?

# Q3: If I run the script and after that modify somepod.pod6, will the changes be detected automatically
# by the CompUnit::PrecompilationDependency and recompiled?

somepod.pod6

=begin pod :kind("Type") :subkind("class") :category("basic")

=TITLE class Cool

=SUBTITLE Object that can be treated as both a string and number

    class Cool is Any { }

=head2 routine abs

Defined as:

    sub abs(Numeric() $x)
    method abs()

No. But what would you use that for?

To tell you the truth I am not very sure, but JJ wants that feature. We will have to use a file to store the names then. Thanks a lot for your help! :D
