associativity of ** operator

Dear all,

In LRM 2.3.1 I believe there is a mistake in operator associativity. According to section 4.2.2 all operators associate left to right except the contional operator. This is the wrong choice in the case of the exponentiation operator '**' because this operator should also associate right to left. With left-to-right associativity this operator becomes equivalent to the multiplication operator except for the leftmost operand.

Here is a small example to show the difference:

2**3**2 = ?

left-to-right associativity:

2**3**2 = (2**3)**2 = 8**2 = 64 = 2**(3*2)

right-to-left associativity:

2**3**2 = 2**(3**2) = 2**9 = 512

This should probably be changed in IEEE 1364 (Verilog) and IEEE 1800 (SystemVerilog) as well.

Cheers,
Marq
