(copy-sequence) is the function you are looking for.
So, IMO the correct behavior in your sample would be that aset signals;
although if you write (setq nbar (copy-sequence (symbol-name 'bar))) it
is ok, as it mangles with a copy of the string.
This is totally bogus behaviour. We should be returning a duplicate copy
of the string to begin with. Unless we make this do the 'right thing' and
reintern 'bar' as 'xar', which would be an even bigger crock.
