Hi,

It seems trimming strings breaks psalm enum type.

Please, take a look to snippet:

I found these snippets:

```php testType($t); ``` ``` Psalm output (using commit f960d71): ERROR: ArgumentTypeCoercion - 16:14 - Argument 1 of B::testType expects 'float'|'int'|'string', parent type string provided ```

```php testType($t); ``` ``` Psalm output (using commit f960d71): No issues! ```

This could be supported by adding a return type provider for trim if you want to give it a shot. Might as well do ltrim and rtrim at the same time.
