REPLs are not new. At all. 165KB is still a lot of pretty-making text. Attitudes like that are why "webapps" eat hundreds of megabytes of memory for tasks where low-tens would be more than enough, even allowing for some slopping programming and lots of abstractions. That 165KB hangs around in memory in probably more than one form, and becomes part of future layout decisions on the page, if they come up.
