Well, looks like Pharo can do all of this for a while. http://pharo-project.org

Type inference is an object of interest: http://gsoc2013.esug.org/projects/type-inference-tools and here are some results : http://concretetypeinference.blogspot.be

The posts are pretty nice to read.

Smalltalk only supports fix and continue (changing code while programming is running), but you still have to manually re-execute your changed code unless you are editing objects directly (in which case, those changes must be saved in an image). Did the Pharo folks add anything more responsive over this?

Comparisons to Smalltalk as well as REPLs are discussed in the essay.
