       PPI::Statement::Sub - Subroutine declaration

	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

       Except for the special BEGIN, CHECK, UNITCHECK, INIT, and END subroutines (which are part
       of PPI::Statement::Scheduled) all subroutine declarations are lexed as a
       PPI::Statement::Sub object.

       Primarily, this means all of the various "sub foo {}" statements, but also forward
       declarations such as "sub foo;" or "sub foo($);". It does not include anonymous
       subroutines, as these are merely part of a normal statement.

       "PPI::Statement::Sub" has a number of methods in addition to the standard PPI::Statement,
       PPI::Node and PPI::Element methods.

       The "name" method returns the name of the subroutine being declared.

       In some rare cases such as a naked "sub" at the end of the file, this may return false.

       If it has one, the "prototype" method returns the subroutine's prototype.  It is returned
       in the same format as "prototype" in PPI::Token::Prototype, cleaned and removed from its

       Returns false if the subroutine does not define a prototype

       With its name and implementation shared with PPI::Statement::Scheduled, the "block" method
       finds and returns the actual Structure object of the code block for this subroutine.

       Returns false if this is a forward declaration, or otherwise does not have a code block.

       The "forward" method returns true if the subroutine declaration is a forward declaration.

       That is, it returns false if the subroutine has a code block, or true if it does not.

       The "reserved" method provides a convenience method for checking to see if this is a
       special reserved subroutine. It does not check against any particular list of reserved sub
       names, but just returns true if the name is all uppercase, as defined in perlsub.

       Note that in the case of BEGIN, CHECK, UNITCHECK, INIT and END, these will be defined as
       PPI::Statement::Scheduled objects, not subroutines.

       Returns true if it is a special reserved subroutine, or false if not.
