I just loved this "section" thing and I wanted to use it in GNU Smalltalk too. Unfortunately, #~ is taken by regex matching there (a la awk). So I am thinking about # which looks somewhat like the `ring' math operator for function application. Also, what about applying sections to blocks? i.e. Object >> ~ aBlock "Left section" ^aBlock curried value: self BlockClosure >> ~ arg2 "Right section" ^[ :arg1 | aBlock value: arg1 value: arg2 ] The polymorphism problem is less pressing, and you can use of course "# Hi Vassili, nice to read your blog.
