The principle is a combination of pragmatism, pain, and then realisation that all memory allocation is slow (allocate less memory).

Lots of D code is fundamentally lazy.

The fastest memory allocator is no-allocation allocation. D has some cool methods for doing that, like the chain template and voldemort types.

For example, chain can be used to "concatenate" two arrays without allocating a byte.
