As a Rubyist, the first thing I wanted to use was 'do', but it is 
already used for 'do-while' loop. :)

'with' in Delphi and VB is used to bring object properties to current 
scope. In Python it is used like 'using' macro in Nemerle. Very
popular keyword.
I think, 'with' keyword must be reserved for future more appropriate 
use... But I like how code with 'with' sounds: "map list with this 
function".

How about:

lst.Map() by (x)
     x + 1

lst.Filter() by (x)
     x == 2

Isn't these sound: "filter by this function"? :) I may be wrong, since I 
   am not a native english speaker.
