In C# you can have a readonly member assignable either at
declaration or constructor time, like this:
class C
{
readonly myClass mc;
this()
{
mc = new myClass();
}
void doSomething()
{
mc = new myClass(); // wrong! result in compiler error, mc is
readonly
}
}
Does D
How can I do that with D?
In C# you can do that:
var filename = @"C:\path\to\my\file.txt";
var file = new Uri(filename).AbsoluteUri;
// file is "file:///C:/path/to/my/file.txt"
