+/**
+ * tal/talloc - an implementation of the tal interface in terms of talloc.
+ *
+ * Tal and talloc are both hierarchical allocators, but have different APIs.
+ * The tal API is mostly a subset of talloc, but if your project already
+ * uses talloc then having both tal and talloc pointers is confusing, and
+ * a waste of resources.
+ *
+ * The standard convention to tell ccan modules to use this instead of
+ * ccan/tal is to define TAL_USE_TALLOC, usually on the commandline.
+ *
+ * Bugs:
+ *     tal_first() and tal_next() can't be implemented.
+ *     tal_set_backend() can only change the error function.
+ *
