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:
