You could make this a one-liner, for no gain and making it harder to debug - an explicitly named intermediate such as sqsum adds no additional overhead compared to the un-named hidden temporary variable the compiler would otherwise use anyway, and of course sqsum can be examined/verified to pinpoint any error more effectively.
<lang Phix>function rms(sequence s)
return sqrt(sqsum/length(s))
end function
?rms(tagset(10))</lang>
