Is there any real reason to use "const"?

We would try to avoid working with pointers directly in read-only 
memory but in any case, I still think that the programmer should 
know what they are doing.

The problem you described is why most language use a "string" 
type that is immutable (in case you point to a string literal) 
but they also have a way to allow you to modify a "string" type 
in case you have allocated memory. So it's always up to you.

So that's how I see it and I can't see it going wrong. I mean, 
you will properly read documentation and learn the language 
right? Well that was sarcastic... no one properly reads 
documentation these days which is the reason why programmers do 
all these stuff bringing all the downsides along. I think we 
should not reward people that don't want to properly learn the 
language.

At the same time I understand that a lot of languages don't have 
a proper tutorial (book, say it however you want) to teach people 
about the language. Some don't even have a full language/library 
reference so even advanced programmer that want to dig cannot 
learn the language. So they can't blame people for not knowing 
the language in the end but this is the language creators fault 
to begin with and I don't plan on doing that. I will make sure 
that people can have learning the language.
