existence_error/2

Description

existence_error(Thing, Culprit)

Throws an existence error. This built-in method is declared private and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of calls:

...,
context(Context),
throw(error(existence_error(Thing,Culprit), Context)).

This allows the user to generate errors in the same format used by the runtime.
