Hi Christian,

Thanks for pointing out this proposal. The actual problem is mkGraph that needs all the many edges created beforehand (that's what I wanted to avoid).
Well, uh, at the risk of being obvious, if you can avoid using fgl functions that call mkGraph, then there is nothing to say that mkGraph has ever to be called, and conversely, if you must use fgl functions that call mkGraph, then there is no way to avoid the fact that it gets the edge labels in a list... :-) A quick grep of the library shows that use of mkGraph is very rare. I haven't chased down the uses of functions that call mkGraph, though, so I don't really know whether many or few functions use mkGraph internally. Of course, you can use (mkGraph = error "mkGraph") and see whether you trip over it at all. Best, - Benja
