How else might one describe a lexical? A short variable name (or assignment
to a symbol table) specific to the current package?
Exactly the opposite. A lexical variable has nothing to do with the
symbol table and does not belong to any package.
A lexical variable is a variable that exists only for the duration of
it's lexical scope. That is, only until the end of the inner-most
enclosing block in which it was defined, or the end of the file if it
was not enclosed in any block.
