Coherent AString and Lexeme implementation.

A Lexeme is any "token" read from input, a lexeme has not yet beeen parsed
and could parse to anything, e.g. a string, an expression, a number, etc.
Lexemes are not (yet?) exposed to the language or ever compiled.

A String is a string literal, which can contain any character directly
except " and \.  There are two special escapes: \" and \\, any other
character following a \ is a syntax error.

Fix garbage collection of REPL objects, leading to type errors from
type variable re-use because a type variable for a given AST's /address/
exists, but that address has actually been deleted and reused by new
(i.e. make top level REPL expressions and types be GC roots).
