#### 3.19.8 Typing Variables
|
||||
|
||||
If an internal variable has a type that is hard or impossible to infer, you can
|
||||
specify its type in a couple ways.

arguments.
|

: If an internal variable has a type that is hard or impossible to infer,
|
||||
specify its type with an annotated assignment - use a colon and type between
|
||||
the variable name and value (the same as is done with function arguments
|
||||
that have a default value):
