How to clone dynamic objects more efficiently than using a serialization/desserialization approach (eg. Set objectB = {}.%FromJSON(objectA.%ToJSON()) ) ?

Why %DynamicObject could not extend %RegisteredObject and its %ConstructClone method (if not inherit it)?

Where are the SQL Show History entries for each user stored?

Set rm=##class(%Regex.Matcher).%New("[0-9]*","Word 123456")
Write rm.ReplaceAll(".")
.W.o.r.d. ..

Why??
