You're right, in this case the functionality is the same. The key
advantage of my patch is that one will be able to pass arguments to
Program if it is a code ref, and I listed the behavior in my first post:

The reason I am doing this is that I have code like
Program => sub {
...
$abc * 2; # $abc is lexical variable outside
},
I do not want Program to be a closure. So a better way to write it is
Program => sub {
my ($abc, $xyz) = @_;
},
ProgramArgs => [$abc, $something_else],
When Program is an array, ProgramArgs get pushed onto it; when it is a
scalar, ProgramArgs are join(' ', @args)'ed and appended to it. There is
no advantage to doing that, of course, but user should be able to specify
ProgramArgs option and get meaningful results in all three cases.
