I had some free time so I decided I should start a simple blog about D,
implementing some unix utilities. I've (unsurprisingly) started with echo.

It's nothing ground-breaking, but every little helps :)
Nice idea! Comments:
- The imperative version writes an extra space at the end (the joiner
version does not have that problem).
- The echo utility has an odd way to process the cmdline: if exactly the
first argument is a -n, then do not writeln at the end.
- It's quite likely the joiner-based version will be slower because it
writes one character at a time. (Would be great to test and discuss
performance as well.)
Here's a conformant implementation for reference:
