//struct Bla {}
alias int Bla;

import std.stdio;

void main()
{
        immutable(Bla[]) _a;
        writeln(_a.length); // prints 0
//        _a.length = 5; // Error: variable _a cannot modify immutable
        immutable(Bla)[] a = _a;
        a.length = 5;  // compiles, but:
        writeln(_a.length); // prints 0

        immutable(Bla[string]) _files;
        immutable(Bla)[string] files = _files;
}
