I have a basic "foreach" loop on an array. If the element of the array meets a condition it is handed to a subroutine that may return either a scalar or a list which should replace that element of the array.

If its a list then splicing it in upsets the indexing of the loop iterator.

Any ideas on how this can be elegantly solved?
