Can you really learn regex in one hour? I learned them so long time ago and in a gradual way that I have no idea how long it would take if you focus on it, but I feel like it would be more than an hour since I think most people would need to play around quite a bit to really grasp them.

There is a way of thinking when you deal with regexes that took me a while to get.

Reading the first chapter of ORiley's Mastering Regular Expressions was what made me get it and that was maybe an hours worth of time.
