Here is a programming technique in LiveCode based on absolute simplicity and ultimate consistency, minimising the number of handlers and facilitating global checks and changes with "Replace All".
Firstly, if the handlers are put into Object Scripts, then there is great redundancy to make maintenance of code extremely difficult as the number of stacks increases.
Secondly, if the handlers are put into Card Scripts, then the number of handlers is reduced, but duplication occurs as the number of cards increases.
Lastly, if the handlers are consolidated into the Stack Script of a single extra stack, then the number of handlers is minimised without redundancy and duplication.
