Example exhibiting the problem:
---
class S
{
immutable int a = void;
this()
{
a = 42;
}
}
---
Error output:
---
test.d(7): Error: cannot modify immutable expression a
---
It compiles and works as expected without the void initializer. It's
understandable behaviour for non-void initializers, but I think the void
initializer should be treated as a special case; fields with void initializers
should be considered uncooked in the constructor.
The example might seem frivolous, but it's important when the field is a
fixed-length array, for which void initializers can make a big difference.
