Suggestions Based on the git diff Output

1. Potential Bug in Array::default Function:

   pub fn Array::default[T]() -> Array[T] {
     []
   }
   

   • The function Array::default is intended to return a default instance of an array of type T. However, the current implementation returns an empty array [], which might not always be the intended default behavior for all types T. This could lead to unexpected behavior if the caller expects a non-empty array or an array initialized with default values of type T.

2. Typo in array_test.mbt:

   @json.inspect!(MX::default(), content={ "mm_num": [] })
   

   • The inspect! macro is used with @json.inspect!, but the macro name inspect! is repeated. It should likely be:

     @json.inspect!(MX::default())
     

   • Additionally, the content parameter seems redundant if it's just repeating the JSON structure that MX::default() would produce.

3. Derive Usage in array_test.mbt:

   struct MX {
     mm_num : Array[Int]
   } derive(Default, ToJson)
   

   • The struct MX derives Default and ToJson. However, the Default derive might not work as expected since the default implementation for Array[Int] is not explicitly defined within the struct itself. This could lead to unexpected behavior if the derived Default does not align with the intended default behavior.
   • Consider explicitly defining the default value for mm_num within the struct or ensuring that the derived Default aligns with the expected behavior.

These observations highlight potential areas of concern that could affect the functionality and maintainability of the code.
