6-The following are design issues for subprograms. Explain the design choices in python for these issues. Please also provide enough examples to illustrate the design choices. • Are local variables statically or dynamically allocated? • Can subprogram definitions appear in other subprogram definitions? • What parameter-passing method or methods are used? • Are the types of the actual parameters checked against the types of the formal parameters? • If subprograms can be passed as parameters and subprograms can be nested, what is the referencing environment of a passed subprogram? • Can subprograms be overloaded? • Can subprograms be generic? • If the language allows nested subprograms, are closures supported?
