PPI::Structure::Unknown - An unknown or unresolved brace structure
PPI::Structure::Unknown is class for braces whose type is unknown, or temporarily unknown.
It primarily exists temporarily inside the lexer. Although some types of braces can be determined immediately at opening, there are a number of different brace types that can only be correctly identified after the braces are closed.
A structure is typed as unknown during this period it is indeterminate.
A PPI::Structure::Unknown object should not ever make it out of the lexer without being converted to its final type. Any time you encounter this class in a PDOM tree it should be considered a bug and reported accordingly.
PPI::Structure::Unknown has no methods beyond those provided by the standard PPI::Structure, PPI::Node and PPI::Element methods.
