|
|
- def foo; .. rescue .. end
|
|
- compile time string concatenation, "hello" "world" => "helloworld"
|
|
- rescue modifier; a rescue b => begin a rescue; b end
|
|
- %w(a\ b\ c abc) => ["a b c", "abc"]
|
|
* class variable (prefix @@?) ??
|
|
* operator !! for rescue. ???
|
|
* objectify symbols
|
|
* objectify characters
|
|
* ../... outside condition invokes operator method too.
|
|
* ... inside condition turns off just before right condition.???
|
|
* package or access control for global variables??
|
|
* named arguments like foo(nation:="german") or foo(nation: "german").
|
|
* method to retrieve argument information (needs new C API)
|
|
* multiple return values, yield values. maybe incompatible ???
|
|
* cascading method invocation ???
|
|
* def Class#method .. end ??
|
|
* class Foo::Bar<Baz .. end, module Boo::Bar .. end

Hacking Interpreter
|
|
|
|
- use eban's fnmatch
|
|
- RUBYOPT environment variable
|
|
- alias $defout $>
|
|
- retrieve STACK_LEVEL_MAX from users' limit.
|
|
- remove end_proc registered out of require only
|
|
- all object made freezable
|
|
* non-blocking open (e.g. for named pipe) for thread
|
|
* avoid blocking with gethostbyname/gethostbyaddr
|
|
* objectify interpreters
|
|
* remove rb_eval() recursions
|
|
* syntax tree -> bytecode ???
|
|
* scrambled script, or script filter
|
|
* setuid ruby
