Just tried to compile and run Base64
The results are:

```
C:      1.46s, 1.9Mb
Rust:   1.49s, 2.4Mb
D LDC2: 1.98s, 4.2Mb
Golang: 2.89s, 10.9Mb
C++:    3.18s, 4.8Mb
```

This test is closer to the author's numbers, but Rust 
implementation isn't faster than the C implementation on my 
machine.

Golang here is faster than C++. The D version was built with 
bounds checks this time.
