Meaning of Program into Your Language and Program in Your Language

Question

I've been reading Code Complete 2. As I am not native english speaker some statements take some time for me to understand. I would like you to describe the difference between these two statements the author made in his book:

1. You should program into Your Language (programming language).
2. You shouldn't program in Your Language.

Why in is bad and into is recommended?

Answer 1

As I understand it, it means to think outside of the bounds of your programming language.

So in means you are thinking in terms of the language, so your thinking is limited by the language itself, and the program you write may not be easily translated into some other language if needed.

But into means you think in algorithms, i.e. freely, then translate into your desired language. So you can easily code in any language you know the syntax of.

But as I have not read the book actually, this may be totally wrong per the context.
