233 // are executed at the end of the method, before it returns, and the
234 // code snippets in the $teardown array are executed in reverse order
235 // when the Wikimedia\ScopedCallback object is consumed.

238 // variables, we have an additional convention: when the array key of
239 // $setup is a string, the string is taken to be the name of the global
240 // variable, and the element value is taken to be the desired new value.
242 // It's acceptable to just do the setup immediately, instead of adding
243 // a closure to $setup, except when the setup action depends on global
244 // variable initialisation being done first. In this case, you have to
