PPI::Document::Fragment - A fragment of a Perl Document
In some situations you might want to work with a fragment of a larger
document. PPI::Document::Fragment is a class intended for this purpose.
It is functionally almost identical to a normal PPI::Document, except
that it is not possible to get line/column positions for the elements
within it, and it does not represent a scope.
Unlike when called on a PPI::Document object, you should not be attempting
to find locations of things within a PPI::Document::Fragment, and thus any
call to the index_locations will print a warning and return undef
instead of attempting to index the locations of the Elements.
Integrate this into the rest of PPI so it has actual practical uses. The most obvious would be to implement arbitrary cut/copy/paste more easily.
See the support section in the main module.
