Why isn't Python very good for functional programming? [closed]
...tic currying, make point-free style overly verbose, don't have lazy lists, etc. So, if iterators instead of lazy lists makes Python a bad functional language, having neither must make CaML a terrible functional language?

Why don't Java Generics support primitive types?

How do I use extern to share variables between source files?
...er links unless you override the
default with -fcommon (or use attributes, etc — see the link).
The next two files complete the source for prog2:
prog2.h
extern void dec(void);
extern void put(void);
extern void inc(void);
prog2.c
#include "prog2.h"
#include <stdio.h>
int main(void)

What is the most pythonic way to check if an object is a number?
...s scalar-like. If you have values of different type (i.e. string, numeric, etc.) coming through, then the logic of your program may need some work - how did you end up trying to multiply a string by a numeric vector in the first place?

windows service vs scheduled task

From a user's POV, I wonder which is easier to control. Both services and scheduled tasks are pretty much out of reach for most non-technical users, i.e. they won't even realize they exist and can be configured / stoppe...
Does Java have something like C#'s ref and out keywords?
...ould be expanded on some. You can only pass primitives (int, short, char, etc.) as value. And no, there is no out.

Freely convert between List and IEnumerable
...(y), selector(x)));
}
Then you can use:
list.Sort(x=>x.SomeProp); // etc
This updates the existing list in the same way that List<T>.Sort usually does.

Return array in a function
...rgv[]){
int arr[] = { 1,2,3,4,5 };
// arr[0] == 1
// arr[1] == 2 etc
int result = fillarr(arr);
// arr[0] == 10
// arr[1] == 5
return 0;
}
I suggest you might want to consider putting a length into your fillarr function like
this.
int * fillarr(int arr[], int length)
T...
