${associativeArray[*]} and ${associativeArray[@]} are
special and expand to value of all elements similarly to
Bourne's "$@" and "$*". That's only when literal. With k=*;
${associativeArray[$k]} still gets you the value for the literal
"*" key like ${associativeArray["*"]} or even
${associativeArray[""*]}.
