My point exactly.

I am typing this in an application running in a GUI, yet can't use it to
send you an example of a graphical notation. The outliner only allows
you to type text in it to define a method, even though it is a very
nice graphical notation of an object.

And this confirms my viewpoints there is no one-to-one
mapping. Different functionalities are involved.

It is not a rough mapping - it is an exact mapping which an automatic
tool can use to translate from one notation to the other.

I see! It is like free-hand sketch and then technical drawing!

But you are the one who said:

Sure! I believe the conundrum might be solved if one builds programming
languages inspired by what happens in domain model and architectures.
And yet the programming language has its own development!

I showed you three different forms for the same content, and hope you
now see the problem with this. In practice, some forms are more
convenient than others.

I see. Thank you for the detailed explanation.
