In order to make D more useful for writing numerical code I would like to suggest the following extensions for built-in functions:

1. Generate random arrays

2. Arithmetic operations with arrays

3. Mathematical functions evaluated element-wise for arrays

I am aware of the existence of mir-glas, which will eventually satisfy 2. As for 1. and 3. I guess it is just a matter of method overloading.

Eventually, it would be great to have a Rosetta stone to help newcomers start using D for numerical computations.
