Re: purple letters

For my part, when I designed my programming language, I intentionally did not 
use single-letter names for any keywords or reserved words or system-defined 
entities etc, and all built-ins were either 2+ letters or were symbols.  As a 
result, single-letter names are available/reserved for end users as barewords to 
name their own (presumably narrow-lexical-scope) stuff, without having to guess 
which letters they may use. -- Darren Duncan
