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
