Description

I noticed today that if a model constructor fails parameter validation it reverts to the default with a warning.

I find this behavior confusing. Normally invalid constructors lead to an error. Alternatively, I can imagine getting frustrated if an overzealous maintainer improperly restricted a parameter range, in which case the thing to do would be to allow the user-provided argument with an error. Either way, reverting to the default seems like a very strange behavior, thoughts?

Research direction

No file, test, or entry point is named. Start by locating model constructor parameter validation and the code that falls back to defaults with a warning, then reproduce the behavior with an invalid parameter. The desired outcome still needs maintainer agreement: error on invalid input or preserve the user argument while reporting the validation failure.
