Hmm… I think that's pretty much what Brendan did, although he likely started with Self instead of Smalltalk. JavaScript makes a strong emphasis on objects, and had closures from the beginning. Then it has a Java-ish syntax. As for actually implementing a smaltalk interpreter, it can now be done in 300 lines: http://www.youtube.com/watch?v=EGeN2IC7N0Q http://www.youtube.com/watch?v=EGeN2IC7N0Q (I believe he used Maru http://piumarta.com/software/maru/ http://piumarta.com/software/maru/ ) With current techniques, a language specialist can implement Smalltalk in a day. I'm not that strong, though. It could take me from a week to a month, depending on how much I need to learn. (Parsing the syntax is easy, but I'm less sure about the semantics.)
