In C, this would not be valid. So the question for me now is:
is const char* in D different from C?
Yes, const char* in D reads as const(char*), so it is a char*
that cannot be modified.
This is similar to the C code:
char *const text = "Hello";
However, because of transitivity, the characters also can't be
modified (unlike C).
For a mutable pointer to const characters, you indeed do
const(char)*.

C++ has a const system that is closer to D's than any other
language, but it still has huge differences:
- const is not transitive
- no immutables
- const objects can have mutable members
- const can be legally cast away and the data modified
- const T and T are not always distinct types
