Pythonic Module

For those transitioning from Python, curious about Chapel, the Pythonic module might be nice to take a look at. It contains a set of helper functions mimicing the functionality of some of the functions built into Python such as enumerate, xrange, range, among others.

If it is useful it should probably be made available in a more convenient form, than this.

module Pythonic {

iter enumerate(iterable) {
    for zipped in zip(1.. , iterable) {
        yield zipped;
    }
}

iter xrange(nelements: int) {
    for i in 0..nelements-1 by 1 {
        yield i;
    }
}

iter xrange(start: int, stop: int) {
    for i in start..stop-1 by 1 {
        yield i;
    }
}

iter xrange(start: int, stop: int, step: int) {
    for i in start..stop-1 by step {
        yield i;
    }
}

//
// Python equivalents
//

// These should return 1D arrays?
proc range(nelements) {

}

proc range(start, stop) {
    
}

proc range(start, stop, step) {

}

//
//  NumPy Equivalents
//
iter arange(start, stop, step) {
    yield 1;    
}

//
// Hmmm how about parallel iterators? Should the above instead be forall?
// How about parallel zipped iterators?
