This method advances the element referenced by the $token variable past the current token and any subsequent whitespace or delimiter tokens.

This method returns undef to indicate that a delimiter element does not yield an expression.

This method is called when a keyword expects a block argument. If a delimiter follows where a block is expected then it is assumed that the block continues until a corresponding end token (a terminator token, not to be confused with a cyborg sent from the future to kill Sarah Connor).

    [% if foo %]
       ...    ^delimiter starts block
    [% end %]
       ^terminator ends block


    [% if foo;
       ...   ^delimiter starts block
       end
    %] ^terminator ends block

It parses a block of content, checks that the terminator token is end, and also, if any fragment is defined that it corresponds to the keyword opening the block.

[% if foo;
    ...
   end#if
%]

The opening keyword may also have a fragment defined.

%%  for#outer x in X
%%      for#inner y in Y
            ...
%%      end#inner
%%  end#outer

If a fragment is specified for an end token then it must match the keyword (e.g. if, for, etc), or the fragment name specified with the keyword, if there is one (e.g. outer and inner in the above example). Otherwise a syntax error will be thrown.

This method is called by a Template::TT3::View object as part of the double dispatch process that is used to render views of template elements. It calls the view_delimiter() method against the view object passed as the only argument, $view. It passes itself as an argument to the view_delimiter() method.

This is defined as the literal keyword end and denotes the terminator token that indicates the end of a block. Subclasses may redefine this constant method to return a different keyword.
