Investigate options for sniffs for catching exceptions. about yoastcs HOT 3 OPEN

Two questions:

1. Is this only global/namespaced function calls or also method calls ?
2. Is there a list available of the functions which throw exceptions ?
   This would need to be a list-based sniff as 1) PHPCS only scans a codebase once, so can't keep track of where it has seen a throw statement and 2) add-on plugins may use functions which throw from Free/Premium.

This would also be for both function calls as well as for methods. For methods there'd be the complexity of finding out what the object is, can PHPCS determine this if either the object is passed as a type-hinted argument, constructed in the same function or is a type-hinted property?

Although PHPCS only scanning once does make it even more complex. Ideally we'd be able to detect which functions throw exceptions, adding free and/or premium as a dev-dependency to projects which use them to ensure the code is also available there.

First thing that comes to mind would be to use https://github.com/nikic/PHP-Parser to dynamically create a list of all functions and methods that throw exceptions and use that as the basis for a sniff.

Investigate whether PHPStan (or one of the addons) or Psalm can do this. If not: close.
