Summary

A PygmentsLexer-like object that only builds the real lexer (and imports the pygments submodule backing it) the first time it's actually asked to highlight something.

Extended Summary

Most sessions only ever use the Python lexer; building all the per-%%magic lexers (bash, html, javascript, perl, ruby, latex...) up front measurably slows down every terminal startup for languages that may never come up in that session.
