This is more a question of Perl's syntax than a question about exec in particular. You can use any standard Perl method to construct a list, and pass that list to exec. What you have is a very reasonable method of doing that. borisz provided another example, and here are a few more:

my @args = ("arg1", "arg2", "arg3");
exec "myProcess.exe", @args; # array will be smashed into a list

my %args = (
  --arg1 => 'val1',
  --arg2 => 'val2',
  --arg3 => 'val3',
);
exec "myProcess.exe", %args; # hash will be smashed into a list

my @args = qw(arg1 arg2 arg3); # a bit of syntax sugar
exec "myProcess.exe", map { "--$_ 'foo'" } @args; # map returns a list

As you can see, there are many ways to make lists in Perl. Which one you pick depends on the situation, but, like I said, the example you've shown is very reasonable.
