    SubjectGeneric list push/pop
    I took a run at writing generic single-linked list push and pop macros, to be 
    used in the form:

    push_list(foo_list, foo_node);

    foo_node = pop_list(foo_list);

    They came out predictably ugly:

    #define push_list(_LIST_, _NODE_) \
    _NODE_->next = _LIST_; \
    _LIST_ =_NODE_;

    #define pop_list(_LIST_) ({ \
    typeof(_LIST_) _NODE_ = _LIST_; \
    _LIST_ = _LIST_->next; \
    _NODE_; })

    These work but imho, they are too ugly to live. For one thing, they assume
    the link field is named 'next' and I don't see a nice way around that.
    Before moving them to my scraps.c file I thought I'd let other people throw
    some tomatoes at them.
