lib.misc.foldArgs

The following is the current implementation of this function.

merger: f: init: x:
    let
      arg = (merger init (defaultMergeArg init x));
      # now add the function with composed args already applied to the final attrs
      base = (
        setAttrMerge "passthru" { } (f arg) (
          z:
          z
          // {
            function = foldArgs merger f arg;
            args = (attrByPath [ "passthru" "args" ] { } z) // x;
          }
        )
      );
      withStdOverrides = base // {
        override = base.passthru.function;
      };
    in
    withStdOverrides
