I suggest to implement a new function similar to
GetNumberSequenceArray() that additionally accepts and tries to convert
strings and puts a double error to the array element if it fails, not
> Currently I think a proper solution would be to check whether we have a real non-empty string before we convert it to numeric and push an error when conversion to numeric fails; i.e. expand on my original patch of GetNumberSequenceArray().
Please don't merge it into GetNumberSequenceArray(), for performance
reasons. Create a new function instead.
