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).
Woops, missed that.
- 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.
As mentioned in the blog, i'll be covering the various flags
later.
- 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.)
I plan on continuing both versions through successive posts, so
when they're complete I'll do a head-to-head between them,
including performance.
