merge

Merge two or more dictionaries into one, giving precedence to the dest dictionary:

$newdict := merge $dest $source1 $source2

This is a deep merge operation but not a deep copy operation. Nested objects that are merged are the same instance on both dicts. If you want a deep copy along with the merge than use the deepCopy function along with merging. For example,

deepCopy $source | merge $dest

mustMerge will return an error in case of unsuccessful merge.
