I used it little, just to hack surf and jumanji, but I found insanely_long_function_names, poor docs of what allocates or frees what, wanton type synonyms, and generally a tangled mess. I gave up. This may not be glib alone, but glib surely seems guilty too. > I _have_ used C++ fairly extensively this -> beSorry (); >> including, particularly, polymorphism and composability. > > I don't know what you mean by this. (I remember the buzzwords, but...) Polymorphism: not need to rewrite essentially the same code for each type. Haskell wins at this, but is not quite a systems language (^_~) C at least has void pointers, which work in some cases. Composability: write functions to do one thing well, and have them call other functions, perhaps passed as arguments, to do other things, or better yet, not do them at all.

Ah yes, "engineer competence doubles every 18 months" (^_^) Cheers, Strake
