When creating code (with Apps or Logic Block), there are simple errors that can be predicted.

[Example]
When declare a Python function, 'default value parameter' should always follow 'non-default value parameter'.
If not, error.

But visual python is possible this situation on Logic Block.

[I think]
When user creates function, if error is expected, it is better to show a 'warning message'.

[Question to Maintainers]
I wonder that if you don't care about this kind of problem.
Are you going to ignore all predicted error? for increasing user's freedom?
