Fail to parse expression inside parenthesis for post increment/decrement

[mingodad]

Here is a sample test to show the problem:

int fib(int n)
{
    if(n < 2) return 1;
    return fib(n-2)+fib(n-1);
}

int addOneFirst(int &n)
{
	return ++(n);
}

int addOneAfter(int &n)
{
	return (n)++;
}

int minusOneFirst(int &n)
{
	return --(n);
}

int minusOneAfter(int &n)
{
	return (n)--;
}

Output:

test.cpp:14:14: expected an expression
	return (n)++;
	            ^
test.cpp:24:14: expected an expression
	return (n)--;
	            ^

@mingodad this looks like an ambiguity between nested expressions and prefixes of C-style casts. I will push a temporary workaround to resolve these kind of parse conflicts until we have the type checker running during parsing. Thanks for the report.
