Well, that's one way you can do it, but it causes a ton of headaches,
e.g. because
exec "echo <user's text goes here>"
gets shell interpretation and fails, so by way of example only, Perl 5
allows for both usages depending on what you pass it. Parrot could
easily make the distinction based on being passed a string value or a
PMC array of some sort and end up with roughly the same functionality as
Perl (though Perl itself would not use this as-is, as it decides further
based on the content of the string, and will call raw exec(2) on the
results of splitting the string on whitespace if no shell metacharacters
occur, but I think that's a bit too much Perlishness to put in Parrot).
Either way, Parrot really HAS to provide a raw POSIX exec, as it cannot
be faked from a shell-using variant correctly.
