say $line->as_string;
}Description
A App::Sqitch::Plan::Change represents a change as parsed from a plan file. In addition to the interface inherited from App::Sqitch::Plan::Line, it offers interfaces for parsing dependencies from the deploy script, as well as for opening the deploy, revert, and test scripts.

my $op_name_dependencies = $change->format_op_name_dependencies;Like format_name_with_dependencies, but includes the operator, if present.
format_planner
my $planner = $change->format_planner;Returns a string formatted with the name and email address of the user who added the change to the plan.
deploy_handle
my $fh = $change->deploy_handle;Returns an IO::File file handle, opened for reading, for the deploy script for the change.

test_handle
my $fh = $change->test_handle;Returns an IO::File file handle, opened for reading, for the test script for the change.
note_prompt
my $prompt = $change->note_prompt(
for => 'rework',
scripts => [$change->deploy_file, $change->revert_file],
);Overrides the implementation from App::Sqitch::Plan::Line to add the files parameter. This is a list of the files to be created for the command. These will usually be the deploy, revert, and test files, but the caller might not be creating all of them, so it needs to pass the list.
