===EBNF===

This solution uses Factor's extended Backus-Naur form (EBNF) language to define a grammar for parsing numerical/alphabetical suffix numbers. The goal was to describe as much of the suffix-number as possible in a declarative manner, minimizing the use of actions (Factor code that is run on a rule before being added to the abstract syntax tree) and helper functions. The biggest departure from this goal was to parse the metric/binary suffixes based on their index in a collection, as this method is less verbose than defining a rule for each suffix.

Note: I am blatantly and deliberately ignoring the task guidelines for formatting the output. It has no bearing on the core of the task. If you really, ''really'','' '''REALLY''' ''want to see badly formatted output, uncomment the last line.
