I would like to also suggest a |
What would the semantics of this method be? |

Ah, sorry. I mean a method that would remove all elements from the given array, resetting its length to 0. |
|
Sorry, I guess it would be presumably be named whatever the analogous thing is in Python; I just suggested the first name that came to mind, I didn't think about what the naming convention here is! |

You can set the length of a dynamic array to zero by either using an empty list literal or using the special empty function my_array: DynArray[uint256, 7] = [ 1,2,3]
my_array.pop()
my_array = [] # set length to zero
my_array = empty(DynArray[uint256,7]) # same thing |

Oh, sorry, I had no idea all that was legal! Disregard my request, then. Thanks! |
