#check_QualifiedName(o) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

No checking takes place - all expressions using a QualifiedName need to check. This because the rules are slightly different depending on the container (A variable allows a numeric start, but not other names). This means that (if the lexer/parser so chooses) a QualifiedName can be anything when it represents a Bare Word and evaluates to a String.
