A typecast itself is also type checked to ensure the conversion specified is a valid one: A typecast itself is also type checked to ensure the conversion is made to a subtype of the expression's type or `any`:
```lua ```lua
local number = 1 local numericValue = 1
local value = number :: any -- ok, 'number' is a subtype of 'any' local value = numericValue :: any -- ok, all expressions may be cast to 'any'
local flag = number :: boolean -- not ok, invalid 'number' to 'boolean' conversion local flag = numericValue :: boolean -- not ok, invalid 'number' to 'boolean' conversion
``` ```
