@VincentLanglet that's something you'd exclude manually via config.

class_exists checks are also quite common and would probably also suffer from the same issue.

`function_exists()` is a runtime expression with another runtime expression
as parameter. This can only be used if:
* The parameter is a constant expression
* The `\function_exists` symbol is referenced absolutely or via `use
function`.
In either way, that is not something this library should go in, as the
complexity explodes massively, and every conditional leads to two
separately checked scopes.

I have code similar to:
if (function_exists('xdebug_get_function_stack')) { $trace = array_slice(array_reverse(xdebug_get_function_stack()), 4);}
So running this with XDebug extension would get the trace differently, but
it could work without XDebug. There could be other conditional uses of a
function or a class, especially for backwards-compatibility.
However, the checker complains about these function uses as the parses
doesn't detect the function_exists condition.

I just encounter the issue with code like
if (class_exists(CacheTokenParser::class)) {
$this->addTokenParser(new CacheTokenParser());
}
It's the only use of CacheTokenParser and it's reported as an error by composer-require-checker.
But not sure it can be solved.
