Validation errors should be able to indicate that a single error should be produced without collecting all of the details ahead of time
In general, validation is lazy -- if only one error is needed (in the sense that it is known that an instance is invalid), only one is produced.
There are however (somewhat unintentional) exceptions.
E.g.:
anyOfandoneOfcalculate the.contextof the first error they yield by calculating all sub-errors that were generated. This is becauseValidationError.contextneeds to be provided on__init__.dependentRequired, on the other hand, yields many errors, one for each missing required property (see also #119)
What's happening in these situations is that the validation function knows an error has occurred -- it wants to yield an error, but in order to do so, it needs to calculate the full details required so that the error is "complete".
We should instead have a way to indicate a validation error has occurred, but delay fully calculating its contents until/unless they are requested.
