emacs-ide.md is a little out of date

Nobody has claimed this yet.

I suggest to update the following two points:

> Dynamic scope is everywhere

Elisp had had optional lexical binding for a decade by now, if not longer. `lexical-binding: t` is becoming the default right now, the topic is hot on emacs-devel.

With `lexical-binding` set to t, scoping in Elisp feels just like CL's. Some non-variable scoping is still dynamic under the hood but that mostly implies compiled code being slower than necessary, and is basically unnoticeable to most users.

I strongly suggest something like “Dynamic scope might pop unexpectedly here and there; however, this rapidly becomes an unlikely possibility, and compiler(s) warn about it since recently”, and moving it much closer to the end of the list of differences.

> There are no reader (or reader-related) functions

Not entirely true. There are reader-related functions; there is `read`, for example. It's just in C and the reader is not extensible with Elisp. The phrasing may confuse people.

See also https://github.com/mishoo/elisp-reader.el I didn't try it but I think it's worthy of mentioning, e.g.: “See, however, mishoo/elisp-reader.el”

Open emacs-ide.md and review the sections titled “Dynamic scope is everywhere” and “There are no reader (or reader-related) functions.” Update both explanations to reflect lexical-binding and the existence of read and reader-related functions, and consider mentioning mishoo/elisp-reader.el. Done means the two statements are accurate and the suggested reference is included where appropriate.
