Implementation's good, but the concept and idea is completely useless at least for Objective-C/Cocoa. All the symbol names of the Cocoa are strictly designed to be used with auto-completing IDE support, not bare editor. That's why they're fine to go such long names. The IDE is a required part for development just like Smalltalk. And a lot of other language/libraries/frameworks are also silently presume auto-completion support. Even on C/C++. I highly doubt usefulness of this even on other languages. Maybe it would be more important to be familiar with specific auto-completion IDE behavior rather than training yourself to type faster.
