This was originally meant as a convenience but prevents possible
functionality. For example:
-- Get the keys of the table with even values
local t = { a = 1, b = 2, c = 3, d = 4 }
vim.iter(t):map(function(k, v)
if v % 2 == 0 then return k end
end):totable()
The example above would not work, because the map() function returns
only a single value, and cannot be converted back into a table (there
are many such examples like this).
Instead, to convert an iterator into a map-like table, users can use
fold():
vim.iter(t):fold({}, function(t, k, v)
t[k] = v
return t
end)
If pack() is called with a single value, it does not create a table; it
simply returns the value it is passed. When unpack is called with a
table argument, it interprets that table as a list of values that were
packed together into a table.
This causes a problem when the single value being packed is _itself_ a
table. pack() will not place it into another table, but unpack() sees
the table argument and tries to unpack it.
To fix this, we add a simple "tag" to packed table values so that
unpack() only attempts to unpack tables that have this tag. Other tables
are left alone. The tag is simply the length of the table.
Problem: Jenkinsfiles are not recognized as groovy.
Solution: Add a pattern for Jenkinsfiles. (closesvim/vim#12236)

vim.iter wraps a table or iterator function into an `Iter` object with
methods such as `filter`, `map`, and `fold` which can be chained to
produce iterator pipelines that do not create new tables at each step.
- vim.diagnostic.config() now accepts a function for the virtual_text.prefix
option, which allows for rendering e.g., diagnostic severities differently.
Problem: C++ 20 modules are not recognized.
Solution: Add patterns to recognize C++ 20 modules as "cpp". (Ben Jackson,

feat(lua)!: add stricter vim.tbl_islist(), rename vim.tbl_isarray()
Problem: `vim.tbl_islist` allows gaps in tables with integer keys
("arrays").
Solution: Rename `vim.tbl_islist` to `vim.tbl_isarray`, add new
`vim.tbl.islist` that checks for consecutive integer keys that start
from 1.
* feat(lua): vim.tbl_contains supports general tables and predicates
Problem: `vim.tbl_contains` only works for list-like tables (integer
keys without gaps) and primitive values (in particular, not for nested
tables).
Solution: Rename `vim.tbl_contains` to `vim.list_contains` and add new
`vim.tbl_contains` that works for general tables and optionally allows
`value` to be a predicate function that is checked for every key.
The first argument which is non-nil is returned. This is useful when
using nested default values (e.g. in the EditorConfig plugin).
Before:
local enable = vim.F.if_nil(vim.b.editorconfig, vim.F.if_nil(vim.g.editorconfig, true))
After:
local enable = vim.F.if_nil(vim.b.editorconfig, vim.g.editorconfig, true)
Problem:
Codebase inconsistently binds vim.api onto a or api.
Solution:
Use api everywhere. a as an identifier is too short to have at the
module level.
Problem: .fs files are falsely recognized as forth files.
Solution: Check 100 lines for something that looks like forth. (Johan

Whenever we run fs_stat() on a path, save this information in the loader
so it can be re-used.
- Loader.loadfile: Remove arguments `hash` as it is no longer needed.
- Loader.loader: Use _G.loadstring instead of Loader.load
This allows plugins to wrap loadstring to inspection and profiling
- factor out read file logic
Problem: Livebook files are not recognized.
Solution: Add a pattern for Livebook files. (Mathias Jean Johansen,
