Search this site for ValidQ. People share insights here, which come from a variety of sources. I learned about ValidQ from a post on this site.

Indeed this is very interesting, we can get a lot of insights. But it still a mystery for me how @JsonB was able to find the ValidQ from the functions definitions. Specially when he says: Observing the fact that valid Function objects seem to be marked as ValidQ we can use

@GarouDan my deepest apologies. You want to use ”GeneralUtilities`” within Needs, as described here.

@GarouDan try exploring the private context, so using ”System`Private`*” within Names. I had given the truncated example in an attempt to be generalized, and also laziness when responding on mobile. As for using the search in the documentation center, I doubt you would find something of the nature of ValidQ. However, you might find some useful information using the developer tools to print the definition of the function/symbol/context you are interested in.

@CATrevillian, unfortunately Names[“System*”]` does not contain any reference to ValidQ. Also using the Mathematica search nothing appears. About searching here, I tried "spelunking tools" and it seems interesting, but I didn't find yet a place with a collection of these kind of tools to use. It would be very useful for me.

@GarouDan you can use techniques such as Names[“System`*”] or related to find those sorts of things. Also try searching “spelunking tools” in the search bar here. And looking into the developer tools would be helpful, too.

One other thing that I'd like to ask. How did you find about SystemPrivateValidQ? I'd like to use this approach to find how the things are defined in Mathematica in the future?
