Coroutine vs Continuation vs Generator
... asymmetric coroutines. Suffice it to say that they're equivalent, you can convert from one to the other, and asymmetric coroutines--which are the most like generators--are the easier to understand. I was outlining how one might implement asymmetric coroutines in Python.)

...Vector等引用着。
例:
Static Vector v = new Vector(10);
for (int i = 1; i<100; i++)
{
Object o = new Object();
v.add(o);

It's possible to "make" a symbol based on primitive data type by calling Symbol(data).
In terms of checking the type, nothing changes.

How can the Euclidean distance be calculated with NumPy?
...sive square roots. That'll be much faster. We can also improve in_range by converting it to a generator:
def in_range(origin, range, things):
range_sq = range**2
yield from (thing for thing in things
if distance_sq(origin, thing) <= range_sq)
This especially has benefit...
