Compiling Regular Expressions
This is kind of the opposite of what the poster is asking for, but what does the function study() actually do?
I say it's the opposite, because the FAQ says it takes more time, and that it works on the scalar to be matched rather than the regex, but I might as well ask.
In what circumstances would I study() a string before hitting it with a regex?
Every bit of code is either naturally related to the problem at hand, or else it's an accidental side effect of the fact that you happened to solve the problem using a digital computer.
