+// This is our virtual machine basic type. Reducing of expression will use this
+// type. We will not malloc or new it, but we'll pass it on the stack for speed
+// and stability. 8 bytes should be ok for our stack. This way we won't have to
+// maintain lists on dynamically allocated computation values, and we won't have
+// to cleanup if some error (divide by zero ?) occurs in the middle of a
+// statement. String values are an exception since sdata will point to dynamic
+// data, but since every step of the virtual machine reducing strings will free
+// that data, cleanup will be automatic
