I am very pleased to offer the design in the two languages. But the final winner will be array of counter, which is coming next.

SpinalHDL

class count extends component() {
var cnt = out Reg(UInt(8 bits)) init(0)
cnt := cnt + 1
}

clk and !rst are implied. That is SpinalHDL philosophy of removing verbosity.

AHDL

SUBDESIGN count
(
	clk : Input;
	rst : Input;
	cnt[7..0] : Output;
)
VARAIBLE
	myCnt : LPM_COUNTER WITH (LPM_WIDTH=8, LPM_DIRECTION = "UP");

BEGIN
	myCnt.clock = clk;
	myCnt.aclr  = !rst;
	cnt[]	    = myCnt.q[];
END;
