I am somewhat new to D, and I am trying to receive user input, 
like this, with a prompt:

string str;
writeln("Enter a string: ");
str = readln;
writeln(str);

However, the prompt appears after I enter the input; any reason 
why?

I've trawled the internet for a good hour, but I can't seem to 
find an answer.

Your code is correct, it's your terminal or whatever you use to 
see your program's output that doesn't flush stdout. You can 
force it though:

string str;
writeln("Enter a string: ");
stdout.flush;
str = readln;
write(str);
