I'm pretty sure PowExpression is still wrong.

with 

PowExpression:
                     UnaryExpression
                     UnaryExpression ^^ PowExpression

UnaryExpression:
                     etc

the code -2 ^^ 2 should have the precedence (-2) ^^ 2,
but this is not the case in dmd

assert( -2 ^^ 2 == -(2 ^^ 2)); //passes
assert( -2 ^^ 2 == (-2) ^^ 2); //fails

more evidence, parse.c, parseUnaryExp, line 5823 or thereabouts:

// ^^ is right associative and has higher precedence than the unary operators
