Agreed.  This one's not at all hard to write, just floated the idea to 
see if others saw it suitable to add to the "convenience" functions 
already in the language, such as:

LC has a few things like that. It was nice to see "difference" added to 
that suite fairly recently.

Adding more such commands to operate on values instead of just keys 
would be handy, but not at all necessary.  There are more pressing 
concerns that only the engine team can implement, and scripting in 
LiveCode is something every LiveCode scripter can do.
