 ## Keyword Arguments
 
-`closures_size` (default=500): The size of closures to use in the main generated code. This specifies the size of code blocks across which the compiler cannot optimize. For sufficiently large functions, a larger value means longer compile times but potentially faster execution time.
+`closures_size` (default=0 (off)): The size of closures to use in the main generated code. This specifies the size of code blocks across which the compiler cannot optimize. For sufficiently large functions, a larger value means longer compile times but potentially faster execution time.
