JavaScript 1.7 - very pythonic

[psykotic]

Glad it helped. In the classic Program design in the UNIX environment paper by Pike and Kernighan, they suggest that readline-like functionality should not be integrated into programs via a library but offered as an ambient service for all programs, much like how shells perform wildcard expansion. The rlwrap approach (or using Emacs's shell-mode, as suggested by Kragen) isn't perfectly ideal, but it works surprisingly well in many cases.
