/** @file
*
* Configuration variables to control configurable aspects of wreport's
* behaviour.
*
* Variables are global and thread_local. They are global because they are
* consulted in performance-critical code like Var::seti, and they are
* thread_local so that a thread that changes its own configuration does not
* affect the others.
*
* LocalOverride can be used to perform configuration changes for the duration
* of a scope. Note that if while the override is active you pass control to an
* unrelated part of the code which also uses wreport, the behaviour of that
* code is also changed.

* Whether domain errors on Var assignments raise exceptions.

* If true, domain errors on variable assignments are silent, and the target
* variable gets set to undefined. If false (default), error_domain is raised.

* Temporarily override a variable while this object is in scope.
*
* Note that if the variable is global, then the override is temporally limited
* to the scope, but it is seen by all the functions that reference the
* variable functions.
*
* Example:
* \code
* {
* auto o = options::local_override(options::var_silent_domain_errors, true);
* var.setd(value)
* }
