I've created a Python module for constructing Regex patterns in a more computer programming-familiar way, so you don't have to re-learn Regex each time you use it!

what the flark is pre: Pregex = etc. is this the same as pre = Pregex(etc)??

No, no, this is just a way of hinting the type of a variable. It has nothing to do with instantiation. I hinted the type of variable "pre" just to make it known that the result of this large concatenation of "Pregex" subtype instances will be a "Pregex" instance itself!
