Re: How do you think of...

Since I only got back from vacation, I'm replying to this thread
late.  To avoid clutter, I'm replying to 5 messages all in this
one email.  Skip what you want:

I read it like it were Ruby code:

    for x in a; p x; end

If I had to read it out loud over the phone, I might read:

    for each x in a, p x.

When I read your code, before I got to the 'How do you read the
"this line" line?' I definitely (in my head) read the code as:

    on each x from a, p x.

However, that's because when I see .each, I skip over to the
block and look at it.  If the block weren't a one-liner, I
would read it as:

    on each element from a,
    using |...|
    do {...}

Remove the "each" and "do" and add some semicolons and an "end" and
it _is_ an actual use of the "for" statement.

I would call Albert's version a "verbose, human-readable version"
of the use of the "for" statement.

What is the sound of one line of code clapping?

Damn, you beat me to it.  ;-)

"Do p() using x to each element in a."

This is what happens when you're Japanese and learn to read
from right-to-left.  My guess is this is how a native Japanese
reader would read the line of Ruby code and IMHO it's quite
intuitive.

"All your 'x' are belong to 'a'."

Sorry, couldn't resist.
