[f9c31f3cd8] Fixed the null dereference bug when directly wrote "case 1 when 2: 3" in REPL. It was due to null LexPosition in the AST. Now AST.pos !is null is an invariant of AST. (user: kinaba, tags: trunk)

[c75f0d5f1e] Enriched the runtime. a.b is now runtime error, not undefined value if the field b does not exist. Added rand(n) and gensym(). (user: kinaba, tags: trunk)
