25Tornado Documentation, Release 6.5.1 For 404 errors, use the default_handler_class Application setting. This handler should override prepare instead of a more specific method like get() so it works with to them. To put your tem- plate files in a different directory, use the template_path Application setting (or override RequestHandler. get_template_path if you have different template paths for different location, subclass tornado.template.BaseLoader and pass an instance as the template_loader application setting.

setindex!) mutates an existing array object in memory, accessible via either a or b. Subsequently setting a = 3.14159 does not change this array, it simply binds a to aCHAPTER 4. VARIABLES 14 different types in other languages. Declaring a function argument or a field as Union{T, Nothing} allows setting it either to a value of type T, or to nothing to indicate that there is no value. See this FAQ entry building packages. You can also debug some precompilation failures with environment variables. Setting JULIA_VERBOSE_LINKING=true may help resolve failures in linking shared libraries of compiled native
