std.conv does not support conversion from a hexadecimal string to an 
integer. Is there a technical reason for this limitation?

This is the best I could do, can it be improved still?
int i = to!int(parse!float("0x1ap0"));

I am doing: to!(int)(BigInt("0x1a").toInt()); toInt actually returns a long: http://www.d-programming-language.org/phobos/std_bigint.html It's kinda frustrating, but it's there.
