I’ve started learning Squeak, a Smalltalk dialect. This PDF by Wilf LaLonde is a nice read especially for C++/Java programmers trying to learn Smalltalk. Squeak IDE doesn’t have code completion and syntax highlighting so I am using Damien Cassou’s image files which have a built-in code completion tool. You can download eCompletion, a code completion tool separately from here.
