By the standard we use where I work, it would look like this:
sub convert {
my ($args) = @_;
AssertRequiredFields($args, [qw( from to thing )]);
AssertValidFields( $args, [qw( from to thing )]);
...
}
where AssertRequiredFields and AssertValidFields are fairly obvious core utility functions (which confess if the assertion is invalid), and $args is a hashref.
Yes, I know that it looks a little outdated... However, even though the codebase is under active development, some of it is still very old. Since nobody really feels like going back and retrofitting a million lines of code, we continue with the old (but still pretty good) standard.
