I find that it's a problem with most languages. Beyond a certain point a project will start to need infrastructure, documentation, code style guidelines and tests - especially when there's more than one developer. My personal preference is for building a large project as multiple smaller ones, or else leaning on other libraries as much as possible (eg. Numpy, Scipy, pygame)
