Why does the following program write the message 'Foo' twice?void main(string[] args) { pragma(msg, "Foo"); }
The message is not printed by the program, but by the compiler.If you build the program via dmd, the message is only printed once.
If you use rdmd, it will be printed twice, because rdmd invokes dmd once to gather the program's dependencies, and a second time to actually build the program.
