Assigning out/ref parameters in Moq
...on 4.8 (or later) has much improved support for by-ref parameters:
public interface IGobbler
{
bool Gobble(ref int amount);
}

delegate bool GobbleReturns(ref int amount); // needed for Returns
var mock = new Mock<...
Is there a Python equivalent of the C# null-coalescing operator?
... so it works in a boolean context. If the values are not boolean, they are converted to boolean for the purposes of the operator.
Note that the or operator does not return only True or False. Instead, it returns the first operand if the first operand evaluates to true, and it returns the second ope...
Is it possible to read from a InputStream with a timeout?
...the data - that's correct behaviour; there are no available data at that point. As soon as the data are available from the shell, the method returns a value > 0. NB: Cygwin uses cmd.exe too.
Simplest solution (no blocking, so no timeout required)
Just use this:

How do I create an empty array/matrix in NumPy?
...might be best off to keep it in a list until it is finished, and only then convert it into an array.
e.g.
mylist = []
for item in data:
mylist.append(item)
mat = numpy.array(mylist)
item can be a list, an array or any iterable, as long
as each item has the same number of elements.

How does the Comma Operator work
..."or", "not", "xor";
Notice that due to operator precedence, the code is (intentionally!) identical to
(((keywords = "and"), "or"), "not"), "xor";
That is, the first operator called is keywords.operator =("and") which returns a proxy object on which the remaining operator,s are invoked:
keyword...
What is the equivalent of the C++ Pair in Java?
...
I agree with Ian. Java lets you return int; it doesn't force you to create an alias for int every time you use one. Pairs are not very different.

JSON.stringify without quotes on properties?
...
So, what you are looking for is basically an object inspector not a JSON converter. JSON format specifies that all properties must be enclosed in double quotes. Hence there will not be JSON converters to do what you want as that is simply not a JSON format.Specs here:

What really happens in a try { return x; } finally { x = null; } statement?
...entially stores it in a variable and returns afterwards
i.e. similar to:
int tmp;
try {

} finally {

}
return tmp;
for example (using reflector):
static int Test() {
try {
return SomeNumber();
} finally {
Foo();
}
}
compiles to:
