The number of elements in the array is "av_len(av) + 1". Returns -1 if the array is empty. I32 av_len(AV *av) av_make Creates a new AV and populates it with a list of SVs. The SVs are copied into the array, so they may be freed after the call to av_make. The new ...
The scalar keyword returns the number of elements in an array, so we have to change the < (less than) to <= (less than or equal to) when choosing between scalar or %# so the for loop doesn’t access an out-of-index member. If you’re getting confused, that’s the point. ...
