This only works if the function in itself useful. Somehow I don't
think this is the case  the most time. If I need not a function, but a
functionality, there's a chance there is an ets table behind or a
process, some configuration file setup - then the whole "import a
single function" doesn't help, but just adds complications that even
the last helper function has to have a globally unique name...
