"title": "FuncParamType crashes for callable type instances without __name__",
"severity": "medium",
"file": "src/click/types.py",
"symbol": "FuncParamType.__init__ / convert_type",
"cause": "FuncParamType is declared as a wrapper for any Callable, and convert_type falls back to FuncParamType for explicit non-built-in type values, but FuncParamType.__init__ unconditionally assigns self.name = func.__name__. Callable instances commonly implement __call__ without a __name__ attribute, so Click raises AttributeError while defining an option, argument, prompt, or direct FuncParamType instead of accepting the callable converter.",
"impact": "Applications that pass a callable converter object as type= cannot even construct the command. This affects @click.option, click.Argument, click.prompt, and click.types.convert_type directly. A user-facing CLI can fail at import/decorator time with AttributeError before parsing any command line input.",
"evidence": [
"src/click/types.py:185-188 defines FuncParamType with func: Callable and immediately reads func.__name__.",
"src/click/types.py:1218-1259 routes explicit non-built-in values to FuncParamType(guessed).",
"tests/test_m1nd_seeded_callable_type.py:1-17 contains a focused callable-instance reproducer expecting type=UpperCase() to convert hello to HELLO.",
"Runtime probe with PYTHONDONTWRITEBYTECODE=1 PYTHONPATH=src python3 showed @click.option('--value', type=UpperCase()) fails during decoration with AttributeError: 'UpperCase' object has no attribute '__name__'.",
"Runtime sweep showed click.types.convert_type(UpperCase()), click.Argument(['value'], type=UpperCase()), and click.prompt('Value', type=UpperCase()) all fail with the same AttributeError.",
"Boundary probe showed a callable instance that defines __name__ succeeds, confirming the break is the metadata lookup rather than the conversion call itself."
