What new capabilities do user-defined literals add to C++?
...'re out of luck until your lobbying to add your quantum wave functions (or 3D points, or whatever basic type you're using in your field of work) to the C standard as a built-in type succeeds.
In C++11, you just can do it yourself:
Point p = 25_x + 13_y + 3_z ; // 3D point
Is it bloated? No, the nee...
