The Hpricot library allows the following syntax:
This is not idiomatic Ruby, and a novice programmer might not know what it did, or how. UrbanHonking explains how, but James Robertson takes issue over why.
If you are going to bend a language's idiomatic usage, you should have a compelling reason, and I share James' view that this example is not compelling.
But other examples are compelling. In Ruby, I could say this:
That's how it would look in Rails today. But I could do even more exotic things:
Or how about:
One of these choices is clearly better than all the others. (Which one?)
The unconventional wisdom here is that your syntax should be chosen for the domain, not by the language. In order for this to work, you must be able to think creatively about the domain you are working in.
The classic counter-argument is "our developers aren't smart/skilled/experienced enough to take advantage of this." Riiight. If your developers aren't skilled enough to think creatively about the domain you are working in, you have way bigger problems.
