 When calling JAX operations wrapped in a `jax.jit`, then the dtype/shape-checking will happen at trace time. (When JAX traces your function prior to compiling it.) The actual compiled code does not have any dtype/shape-checking, and will therefore still be just as fast as before!

+## `flake8` or Ruff are throwing an error.
 
 In type annotations, strings are used for two different things. Sometimes they're strings. Sometimes they're "forward references", used to refer to a type that will be defined later.
 
 Some tooling in the Python ecosystem assumes that only the latter is true, and will throw spurious errors if you try to use a string just as a string (like we do).
 
-In the case of `flake8`, at least, this is easily resolved. Multi-dimensional arrays (e.g. `Float32[Array, "b c"]`) will throw a very unusual error (F722, syntax error in forward annotation), so you can safely just disable this particular error globally. Uni-dimensional arrays (e.g. `Float32[Array, "x"]`) will throw an error that's actually useful (F821, undefined name), so instead of disabling this globally, you should instead prepend a space to the start of your shape, e.g. `Float32[Array, " x"]`. `jaxtyping` will treat this in the same way, whilst `flake8` will now throw an F722 error that you can disable as before.

 ## Does jaxtyping use [PEP 646](https://www.python.org/dev/peps/pep-0646/) (variadic generics)?
