and there is a more D idiomatic version:

import std.stdio;
import std.algorithm;
import std.file;
import std.path;

int main()
{
	try
	{
		auto dFiles = dirEntries("/proc", SpanMode.shallow)
			.filter!(f => f.isDir)
			.each!((a){writefln("Subdir: %s", a.baseName);});
	}
	catch (FileException fe)
	{
		stderr.writeln(fe.msg);
		return 1;
	}
	return 0;		
}
