fix temp problems:

	[ | foo | ..... ]   " <---- open-coded block "
        foo ...             " <---- still in scope "

    -> push then pop new environment, without increasing nesting level

write liboop in idst

mangle member names ('default' is not a valid member name)

Characters: $\t $\011 etc...

{ include <stdio.h> } and similar...

{ import foo bar baz }
{ include <time.h> <sys/time.h> }

separate compilation
interfaces

compilation to .so

immutable literals

shared literals (1 instance of each value)

_selector _proto _method _bind _alloc -> message sends

(define (class Object) nil ())

(define (send Object integer: anInteger)
  (stdio.printf "Object.integer: %s!\n" (integer-value anInteger))
  self)

(send Object integer: (integer-object 42))
