# [DESCRIPTION](#DESCRIPTION)

Object of the type "PPI::Token::Unknown" exist primarily inside the tokenizer, where they are temporarily brought into existing for a very short time to represent a token that could be one of a number of types.

Generally, they only exist for a character or two, after which they are resolved and converted into the correct type. For an object of this type to survive the parsing process is considered a major bug.

Please report any "PPI::Token::Unknown" you encounter in a PPI::Document object as a bug.
