Checks a parsed nunjucks template, and throws a TemplateSandboxError if a name in it could
change the code the compiler generates:
every variable, filter, loop, set, macro, import and block name must be a plain name (letters,
combining marks, digits, connector punctuation such as _, and $); a filter name can also contain dots
a test name, and an extension's registered name and method, must not contain a quote, a backslash or a line break
a name that every object inherits (toString, hasOwnProperty, ...), or prototype, must not be a
dictionary key, a keyword argument, a macro or call-block argument, a set, loop, import, macro or
block name, or a filter or test name
the name of a called member must not contain a backslash or a line break
a loop variable must not reuse an identifier that the generated loop code uses (context, frame,
runtime, tasks, undefined, ...)
the tree must hold only nunjucks nodes, plain values and regular expression literals
