From Newsgroup: comp.lang.python.announce

Hi All,

I am happy to announce **func-validator 1.2.0** release, this version
provides custom error messages for validators via the "err_msg" optional keyword argument.

This package was inspired by MATLAB’s argument validation framework, bringing a similar level of clarity and structure to Python function definitions.

Below is a quick example:

```python
from typing import Annotated
from func_validator import validate_params, MustBePositive, MustBeNegative

@validate_params
def func(a: Annotated[int, MustBePositive(err_msg="a must be greater
than 0")], b: Annotated[float, MustBeNegative(err_msg="b must be less
than 0")]):
   ...
```
