What do Vim plugin authors want from Vim? [on hold]

Question

Vim has many features that plugin authors can use to achieve their goal. But what is still missing? What could be simplified? What is currently impossible? This is more a poll than a question with the right answer. Please use one request per answer. Use the voting mechanism if you agree with a specific answer/request.

(Given the comments, I guess reddit would be a more appropriate fit for your question.)

So far, the things I'm looking for are, in no particular order:

• a better way and simpler way to fetch the current callstack -- I remember having opened an issue on the subject
• other fast functions that permit to work on lists. At this time, I'd have liked to see find/find_if functions, and a reduce one as well.
• I'd like to see something like my project variables -- but this one would be a big game changer in many ways as it would introduce a notion that don't exist in vim: the notion of project
• Actually, I'd like to see most of the helper functions I have in my lh-vim-lib library to be standard functions, in particular list and dictionary related functions. Other library plugins are probably a good start as well.
• a thread safe environment. For instance, I'd like to highlight thousand of new keywords, or to add them in the spell ignore list without freezing vim. But this means we'll need a thread safe language. This is also a very big change.
