Q: Why not Xah's review of Ruby?

>> Spent about 3 hours looking into Ruby language today.

A. Three hours? I've had belches that lasted longer than that. Of
course, a true master can tell a lot in just a few hours of coding with
a new language...

>> The articles i read in detail are:

Q: Read?!

A: That's what he said.
