My long quest for a usable set of basic structures in C lead me to
basekit. It is BSD and the code is very simple, I like it very much:


It is used in the IO programming language, which is in the same
ballpark as python (very dynamic ala smalltalk) and uses a GC, which
means the allocation strategy used in basekit is viable for VM which
do not depend on reference counting.
