Declares the compilation unit as being in the given namespace. The scope
of the package declaration is from the declaration itself through the end
of the enclosing block, file, or eval (the same as the C<my> operator).
default, empty leading fields are preserved, and empty trailing ones are
deleted. (If all fields are empty, they are considered to be trailing.)

-because it clobbers your subroutine arguments.
+In scalar context, returns the number of fields found.
If EXPR is omitted, splits the C<$_> string. If PATTERN is also omitted,
splits on whitespace (after skipping any leading whitespace). Anything
not end in a newline, it appends the same file/line number text as C<die>
does.

C<die>.
