241 // are executed at the end of the method, before it returns, and the

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