Perl6 is supposed to have lots of features; but it's supposed to be simple (unlike Java) in that if you don't want to use these advanced features (like for example continuations, coroutines with yield, exceptions, quantum-superpositions, multimethods, strong typing, operator overloading, macros, calling parrot or native code, or even just objects), you don't have to use any of them. You should still be able to write one-liners or (basic|fortran|pascal)-like programs in it. (Well, this is the theory, I don't know how much perl6 will actually be like this, I'm still a bit affraid it will not be.)
