| ECMA Section: 15.5.1 The String Constructor called as a Function |
| 15.5.1.1 String(value) |
| 15.5.1.2 String() |
| |
| Description: When String is called as a function rather than as |
| a constructor, it performs a type conversion. |
| - String(value) returns a string value (not a String |
| object) computed by ToString(value) |
| - String() returns the empty string "" |
