mildew.types.array source code

1 /**
2 This module implements how arrays are internally handled. There is no reason to use this instead of constructing a
3 ScriptAny with a D array or using toValue!(ScriptAny[]) on a ScriptAny that stores an array, unless it is necessary
4 to modify the array in place inside a thisObj.
