Quick Start |

Inheriting from `ST_FORMATTING_ROUTINES` adds the feature `format` to the current class. `format` takes two arguments: a string containing formatting specifications and an array of parameters. This array must be an array of references. For example `ARRAY` [`BOOLEAN`] does not work with SmartEiffel. Because `BOOLEAN` does not conform to `ANY` is SmartEiffel 2.1, we need to use `ARRAY` [`DS_CELL` [`BOOLEAN`]] in that case.

`format` returns a `STRING` where all formatting specifications have been replaced by their corresponding formatted parameters.
