As annoying as it is, especially when updating function signatures, I kinda enjoy having separate header files. It clearly defines the public vs. private interface(s), it's a place to put your docstring comments in and a single file that can provide a quick glance to how a module works. Although it is much less practical in C++ than in plain C, when you have to put the whole class definitions (including private member functions) in a header. A good editor/tags system/ide should support jumping between definition and declaration quickly, this definitely makes it a bit less painful (e.g. vim + ctags + cscope work fine).
