Using kcl quant expressions including all/any/map/filter

Hey @Peefy To determine whether all or any elements in a list, dictionary, or set satisfy a certain condition in KCL (Kusion Configuration Language), you can use the quant expressions all, any, map, and filter. The all expression checks if all elements in a collection satisfy a condition, such as all(my_list, lambda x: x > 0) to verify if all elements in my_list are positive. The any expression checks if any element satisfies a condition, like any(my_dict.values(), lambda x: x > 0) to see if any value in my_dict is positive. The map expression applies a function to all elements, for example, map(my_set, lambda x: x x) to square all elements in my_set. The filter expression returns elements that satisfy a condition, such as filter(my_list, lambda x: x > 0) to filter out positive numbers from my_list. Combining these expressions allows for more complex operations, like checking if all squared elements are greater than 10 using all(map(my_list, lambda x: x x), lambda x: x > 10). These quant expressions enable efficient and flexible condition checks on various collection types in KCL.
