 TODO
 ====

+* add `*_by_lua_block` directives for existing `*_by_lua` directives so that we put literal Lua code directly in curly braces instead of an nginx literal string. For example,
+```nginx
 
-Short Term
-----------
+ content_by_lua_block {
+     ngx.say("hello, world\r\n")
+ }
+```
+	which is equivalent to
+```nginx
+
+ content_by_lua '
+     ngx.say("hello, world\\r\\n")
+ ';
+```
+	but the former is much cleaner and nicer.
+* cosocket: implement LuaSocket's unconnected UDP API.
+* add support for implementing general TCP servers instead of HTTP servers in Lua. For example,
+```lua
+
+ tcp {
+     server {
+         listen 11212;
+         handler_by_lua '
+             -- custom Lua code implementing the special TCP server...
+         ';
+     }
+ }
+```
+* add support for implementing general UDP servers instead of HTTP servers in Lua. For example,
+```lua
+
+ udp {
+     server {
+         listen 1953;
+         handler_by_lua '
+             -- custom Lua code implementing the special UDP server...
+         ';
+     }
+ }
+```
+* ssl: implement directives `ssl_certificate_by_lua` and `ssl_certificate_by_lua` to allow using Lua to dynamically serve SSL certificates and keys for downstream SSL handshake.
+* shm: implement a "shared queue API" to complement the existing [shared dict](#lua_shared_dict) API.
+* cosocket: add support in the context of [init_by_lua*](#init_by_lua).
+* cosocket: implement the `bind()` method for stream-typed cosockets.
+* cosocket: pool-based backend concurrency level control: implement automatic `connect` queueing when the backend concurrency exceeds its connection pool limit.
+* [ngx.re](#ngxrematch) API: use `false` instead of `nil` in the resulting match table to indicate non-existent submatch captures, such that we can avoid "holes" in the array table.
 * review and apply Jader H. Silva's patch for `ngx.re.split()`.
 * review and apply vadim-pavlov's patch for [ngx.location.capture](#ngxlocationcapture)'s `extra_headers` option
 * use `ngx_hash_t` to optimize the built-in header look-up process for [ngx.req.set_header](#ngxreqset_header), [ngx.header.HEADER](#ngxheaderheader), and etc.
 * add configure options for different strategies of handling the cosocket connection exceeding in the pools.
 * add directives to run Lua codes when nginx stops.
 * add `ignore_resp_headers`, `ignore_resp_body`, and `ignore_resp` options to [ngx.location.capture](#ngxlocationcapture) and [ngx.location.capture_multi](#ngxlocationcapture_multi) methods, to allow micro performance tuning on the user side.

-Longer Term
------------
 * add automatic Lua code time slicing support by yielding and resuming the Lua VM actively via Lua's debug hooks.
 * add `stat` mode similar to [mod_lua](https://httpd.apache.org/docs/trunk/mod/mod_lua.html).
