I'm not sure what "squint at the dubloons" (Pirate for "study $_") does.
Indeed, study looks at a string and indexes the chars for later regex use - pretty much made redundant by qr though. Here though, it's simply decoration. :)

    study and qr are not the same thing at all. qr compiles a regex string into the data structure that represents that regex in memory. study processes a string that a regex is going to process later. So the difference is that qr speeds up the regex on the right side of =~ and study speeds up the string on the left side.
