+ *

+ * There are a few cautions to observe:
+ *
+ * - Variable's value must not be NULL. If there is no initial value then
+ * LLVMGetUndef() should be used.
+ *
+ * - Variable's value must be kept up-to-date. If the variable is going to be
+ * modified by a function then a pointer should be passed so that its value
+ * is accurate. Failure to do this will cause some of the variables'
+ * transient values to be lost, leading to wrong results.
+ *
+ * - A program should be written from top to bottom, by always appending
+ * instructions to the bottom with a single LLVMBuilderRef. Inserting and/or
+ * modifying existing statements will most likely lead to wrong results.
