The idea of a one-liner is sort of silly when applied to functional programming....

It's only silly if you don't apply a reasonable character limit in your definition.

I would say < 80 is definitely a one-liner, < 100 is more-or-less a one-liner, < 120 is really pushing it. After that, you're cheating. Even Java style guides cut you off after 120.

12 of these "one-liners" fail even the most permissive of these criteria, but, y'know, YMMV. None are over 140.

> None are over 140.

Their limit is at the top of the page:

> 2. How long is a line? Here, we limited users to 132 chars. It's the old line printer standard.

To me all (complex) one liners are bad : they're hard to read and they don't manage errors.

I'd rather go through 5 lines of simple statements than try to decipher a "clever" one liner.

From the fine article : > Open a GUI, read web page, sent it as email

You really want to do that in one line ?

sending someone a link via email is a relatively common task.

why would it be undesirable to write short code that can do that?

Not undesirable, just odd to make a big deal about it. Like making a big deal about Unix pipes. Yeah, when they were invented, okay. Nowadays ... old hack.
