State of Haskell editor/IDE support

This chart describes the support level of each Haskell editor/IDE plug-in combination.

In most cases there is a main plug-in which acts as a base for the provided features.

Each known plug-in has an associated link and tooltip with its name.

Symbol	Support Level
…	Unknown, support is uncertain
🚶	Absent, you are on your own
🚲	Immature, only for early-adopters
🚗	Mature, suitable for most programmers
🚀	The best™ possible experience

Notes:

native support (probably minimal)
via main plug-in
this plug-in needs special config and/or system deps, refer to its documentation

Snippets - Predefined and customizable templates for pieces of code you write often. For example, if you write case, an editor might provide a completion like
```
case ___ of
  __ -> ___
```
Hoogle
REPL Integration - Be able to load/reload a file to e.g. ghci and provide interaction. Autocompletion and syntax highlighting are also welcomed.
