What makes you think the compiler generates code to check if the
content has changed? Surely it would be simpler to just compare
against the current value (changed or otherwise)?
As far as I know there is no difference in efficiency at run-time--and
if there were it would likely be so small as to be truly insignificant
even over multiple iterations.
