How can I determine, for a given user option, what its Customize :type is?
For example, function `user-variable-p' tests whether a symbol is a user
option, but what if I want to test whether a variable is a toggle (binary)
option?
Although not all options that can act as toggles are defined with a simple
":type 'boolean" in Customize (far from it, and there are good reasons for
that), obtaining such :type info would be a start.

Examine its `custom-type' property.

Thanks a lot John-Paul - just what I needed.
I guess this is another one of those things that you need to search the
source code to find - it's not in the Elisp manual.

It is in the symbol property list:
(get 'your-symbol 'custom-type)
