In a language like Unicon/Icon, I can "$include" a source file, I can "link" an ucode (compiled source, unlinked) file, I can "import" a ucode class file, I can put all the source in the same file or I can get the compiler to bring all the files together on the command line and it will basically end up with the same result.
Does Julia provide Base as source to allow you to do anything like the above?
