Does Wolfram|Alpha has any Perl-related content?

Depends on the definition and scope of "Perl-related". Wolfram|Alpha is as related to Perl as Google would be.

We have various kinds of shortcuts on PerlMonks to help us point to helpful web content when trying to explain things. I see Wolfram|Alpha as a way of (at least) describing mathematical notions with better illustration in our posts. Of course, it's not only limited to mathematics. Think of it as a more technical content-targeted version of Google.

An example post could contain:

There are 120 ways of choosing any 3 things from a pile of 10 different ones. (PerlMonk shortcut: [wolfram://10 choose 3|120 ways])

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.
