Given a character string of a simple mathematical expression containing only numbers, parentheses and arithmetic symbols (+ - * /), write a function that evaluates the value of the string expression. If the input is an empty string or when no arguments are passed to the function, the function should output the value of the previous non-empty expression evaluated.
The following restrictions apply:
- The function should only have one (1) line of code, excluding the function start line.
- Semicolons (;) are considered end-of-line characters.
- Please suppress the function end line. Keyword 'end' is not allowed.
- Regular expressions and string manipulation are not allowed.
