This is run at compile time, and the compiler treats any char
array at compile time as an immutable string literal when it
crosses the barrier into run time. Moreover, this would be a
static instance of the initial array; the default reference is
shared across all objects created (so if you modify intArray then
`new` another object, you'll see the modified intArray!).
You almost never want to assign arrays or objects at compile time
like this in a class definition; use constructors instead.
I think the `new char[]` thing being immutable in runtime is a
compiler bug, it makes it immutable but it is still typed as
mutable in the type system. but this whole static init thing is
probably not what you want anyway.
