 46 * simplicity of type naming.  The alternative for structures is to use tags,
 47 * which are named the same as their typedef names (legal in C/C++, and less
 48 * noisy than suffixing the typedef name with "Struct" or "Str").  Instead,
 49 * all .h files that include this file may use the same typedef name, whether
 50 * declaring a pointer to struct type, or defining a member of struct type.
 51 *
 52 * A few fundamental scalar types are defined here too.  Neither the scalar
 53 * nor the struct typedefs should change much, therefore the nearly-global
 54 * make dependency induced by this file should not prove painful.

186 * invocation. Alternately, the 'before' could just return the same value as
187 * in 'closure' to cause the 'after' invocation to be called with the same
188 * 'closure' value as the 'before'.
