SubjectGeneric list push/pop
Date
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);

and
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.
