Lambda expressions are similar to anonymous functions in other languages.
Lambda expressions are open formulas which also specify variables which are to be bound. Evaluation (finding the value of a function call) is then achieved by substituting the bound variables in the lambda expression's body, ...

Now that you have an object, it might be good to figure out what it is. You can use the Get-Member cmdlet to see what an object is and what it contains:
Get-Item c:\windows | Get-Member

Prior to C++17, template deduction cannot deduce the class type for you in a constructor. It must be explicitly specified. Sometimes, however, these types can be very cumbersome or (in the case of lambdas) impossible to name, so we got a proliferation of type factories (like make_pair(), make_tuple(...
Rename the remote named <old> to <new>. All remote-tracking branches and configuration settings for the remote are updated.

Let me explain the idea of it to you on a simple example. Imagine you're working...
Create a new class implementing IXposedHookLoadPackage and implement the handleLoadPackage method:
