Nice! The approach here seems fine to me. I've left some feedback inline about some minor things, but the approval is intended to mean that I'm fine with moving straight to merge without another round of reviewing unless you want to discuss that feedback further.
This adds ValidateSpec, a new decoder Spec that allows one to add custom validations to work with values at decode-time. The validation is run on the value after the wrapped spec is applied to the expression in question. Diagnostics are expected to be returned, with the author having flexibility over whether or not they want to specify a range; if one is not supplied, the range of the wrapped expression is used.
