Bug 10306 – Array ^^ operator doesn't support complex expressions

import std.math; void main() { double[3] a, b, c; double[3] r1 = (a[] - b[]) * c[]; // line 4, OK double[3] aux = a[] - b[]; // OK double[3] r2 = aux[] ^^ 2; // OK double[3] r3 = (a[] - b[]) ^^ 2; // line 7, error double[3] r4 = (a[] - b[])[] ^^ 2; // line 8, error } dmd 2.064alpha gives: temp.d(7): Error: incompatible types for ((a[] - b[]) ^^ (cast(double)2)): 'double[]' and 'double' If you comment out line 7 you receive: temp.d(8): Error: Array operation a[] - b[] not implemented I'd like the ^^ array op support a complex expression as in line 4. Also the error messages are a little confusing.
