*
*
* For a PHP method to be a valid context, it needs to have
* a PHPDocBlock declaring the viewPath parameter as a
* string with the variable name $view.
*
* This convention is necessary, otherwise we would need
* to hard-code the methods accepting view parameters or
* the code-assist would pop up in every QuotesContext.
