Hello Daniel,

i have another idea - program can include statements like

"freeze Fixnum, String, Regexp"

that guarantees to optimizer that appropriate classes will be not
changed after this statements and methods of this classes can be
dispatched as "finalized" (in terms of Java)

but i think that "freeze" will be not very helpful w/o explicit type declarations
