I have two short questions on Smalltalk:

1. Is it possible to create a message at run time and then send it?
For those of you who know LISP, I am asking if Smalltalk has a
facility analogous to the EVAL statement.

2. Can you redefine the system-defined classes (such as integer,
graphic objects, and so forth) to contain a modified set of messages?

	Thanks in advance for any answers or pointers,
