Seeking again at the isInAny function we described there, here's how we might make use of a partly used perform rather than a named helper operate or a lambda.

If we implement zip3 with just one argument, we get a perform that accepts two arguments. Regardless of what arguments we provide to this compound function, its to start with argument will always be the fixed worth we specified.

Pascal system: If You're not only new to Delphi, but in addition new to programming, you might want to study Pascal just a little initially!
