Description

Information depending on the kind.

Not coded as a union for two reasons: i) In that case one of the two members would not be initialized (the constructors in the struct only initialize one if the struct is a union), even with its default constructor, and further attempts to copy that member from another Info into this (for example, in the StepInfo copy constructor and in the case that the other member to copy is RIT, which involves the copy of a map iterator) may produce severe problems due to its previous lack of initialization. ii) Some parsers may need to annotate a terminal (VT) with the rule in course (RIT).
