Also, there's really no reason to be doing anything with char[]
instead of string unless you're specifically planning on
mutating the elements in your string, and casting from a string
literal to a char[] is almost never a good idea, because it
means that you could end up mutating the elements, which would
violate the type system guarantees - since immutable values are
never supposed to be mutated, and the compiler will potentially
make the assumption that an immutable value was not mutated
(string is an alias for immutable(char)[], and string literals
are strings). If you _do_ need to mutate the string for some
reason, then use dup to get a mutable copy rather than casting
the literal, e.g.
char[] wkVarName = "IntVar3".dup;

Probably I misunderstand, but using -betterC:
```
extern (C) void main() {
char[] Name;
Name = "InitName".dup;
// Name = cast(char[])("InitName");
}
```
fails to compile, but
```
extern (C) void main() {
char[] Name;
// Name = "InitName".dup;
Name = cast(char[])("InitName");
}
```
compiles.
