listLimit property
final
QS will limit specifying indices in a List to a maximum index of 20.
Any List members with an index of greater than 20 will instead be converted to a Map with the index as the key.
This is needed to handle cases when someone sent, for example, a[999999999] and it will take significant time to iterate
over this huge List.
This limit can be overridden by passing an listLimit option.
Implementation
final int listLimit;
