/* "The semantics are similar to those of any of the many other
 *  programming languages these control structures appear in.  When the
 *  interpreter sees an "if", it evaluates the test associated with it.
 *  If the test is true, it executes the block associated with it.
 *
 *  If the test of the "if" is false, it evaluates the test of the first
 *  "elsif" (if any).  If the test of "elsif" is true, it runs the
 *  elsif's block.  An elsif may be followed by an elsif, in which case,
 *  the interpreter repeats this process until it runs out of elsifs.
 *
 *  When the interpreter runs out of elsifs, there may be an "else" case.
 *  If there is, and none of the if or elsif tests were true, the
 *  interpreter runs the else's block.
 *
 *  This provides a way of performing exactly one of the blocks in the
 *  chain.
