=head1 NAME

Test2::Tools::Grab - Temporarily intercept all events without adding a scope
level.

=head1 DESCRIPTION

This package provides a function that returns an object that grabs all events.
Once the object is destroyed events will once again be sent to the main hub.

=head1 SYNOPSIS

use Test2::Tools::Grab;

my $grab = grab();

# Generate some events, they are intercepted.
    ok(1, "pass");
    ok(0, "fail");

my $events_a = $grab->flush;

# Generate some more events, they are intercepted.
    ok(1, "pass");
    ok(0, "fail");

my $events_b = $grab->finish;

=head1 EXPORTS

=over 4

=item $grab = grab()

This lets you intercept all events for a section of code without adding
anything to your call stack. This is useful for things that are sensitive to
changes in the stack depth.

my $grab = grab();
        ok(1, 'foo');
        ok(0, 'bar');

my $events = $grab->finish;

is(@$events, 2, "grabbed 2 events.");

If the C<$grab> object is destroyed without calling C<finish()>, it will
automatically clean up after itself and restore the parent hub.

{
        my $grab = grab();
        # Things are grabbed
    }
    # Things are back to normal

By default the hub used has C<no_ending> set to true. This will prevent the hub
from enforcing that you issued a plan and ran at least 1 test. You can turn
enforcement back one like this:

$grab->hub->set_no_ending(0);

With C<no_ending> turned off, C<finish> will run the post-test checks to
enforce the plan and that tests were run. In many cases this will result in
additional events in your events array.
