Why can't C++ be parsed with a LR(1) parser?
...xed as:
int (MyClass::*)(char*) MethodPtr;
this being coherent with the cast operator (int (MyClass::*)(char*))
typedef int type, *type_ptr; could be forbidden too : one line per typedef. Thus it would become
typedef int type;
typedef int *type_ptr;

How do I make calls to a REST api using C#?
...uld be to use RestSharp. You can make calls to REST services and have them cast into POCO objects with very little boilerplate code to actually have to parse through the response. This will not solve your particular error, but answers your overall question of how to make calls to REST services. Havi...
Best way to compare two complex objects
....Equals method (whose execution would be marginally slower due to the type cast).
When you override Object.Equals, you’re also expected to override Object.GetHashCode; I didn’t do so below for the sake of conciseness.

public int Age { get; s...
Copy constructor versus Clone()
... used. It also returns object, which is a pain, since it requires a lot of casting. (And though you specifically mentioned classes in the question, implementing ICloneable on a struct requires boxing.)
A copy constuctor also suffers from one of the problems with ICloneable. It isn't obvious whether...
PreparedStatement IN clause alternatives?
...statement is ... IN (SELECT UNNEST(?::VARCHAR[])) or ... IN (SELECT UNNEST(CAST(? AS VARCHAR[]))). (PS: I don't think ANY works with a SELECT.)

What is the equivalent of the C# 'var' keyword in Java?
...), don't forget that non-virtual methods are affected by the Type they are cast as.
I can't imagine a real world scenario where this is indicative of good design, but this may not work as you expect:
class Foo {
public void Non() {}
public virtual void Virt() {}
}
class Bar : Foo {

JavaScript OOP in NodeJS: how?
...4);
console.log(gExampleSubClass.publicVar);
console.log(gExampleSubClass.CAST("ExampleClass").publicVar);
The code is pure javascript, no transpiling. The example is taken from a number of examples from the official documentation.

Booleans, conditional operators and autoboxing
...nboxing is due to the third operator being of boolean type, like (implicit cast added):
Boolean b = (Boolean) true ? true : false;

How can I check if a string represents an int, without using try/except?
...isdigit()
True
it won't work with '16.0' format, which is similar to int casting in this sense.
edit:
def check_int(s):
if s[0] in ('-', '+'):
return s[1:].isdigit()
return s.isdigit()
