The main purpose of the empty statement is to allow redundant semicolons to be used without causing a syntax error.  For example, in strict Maple syntax there would be no semicolon statement separator following the cube statement below:

However, users who get used to ending all statements with a semicolon are accommodated since, if a semicolon follows i^3 here, then in the view of the Maple parser there is an empty statement prior to the keyword end do.
