} Well, this 1+1 is evaluated when you assign to bar, not when you do >&$bar...

} results in the file 1+1 being created with contents 'something'.

You missed the very important "integer" declaration.  If you change your
test to begin

% integer foo=1+1

you will get a very different result.  Because the variables created with
{foo}>& are implicitly given integer type, you have to try >&$foo with an
integer foo, not an ordinary scalar foo.
