Feature requests

[Spacen Jasset]

I have some features requests, some of which are small. Is there a way 
that these should be raised?

For example, this trivial feature could go in phobos2.std.math and tango:

float degToRad(float deg)
{
	return deg * PI / 180;
}

float radToDeg(float rad)
{
	return (180 * rad) / PI;
}
