Hi,
The manual only mentions `>&-` and `<&-`. Do `>& -` and `<& -` also work?
I tried the following and I don't see errors. But I can not be sure
whether `>& -` and `<& -` are exactly the same as `>&-` and `<&-`.
$ exec 42>& -
$ exec 42<& -
Could anybody confirm?
If they both work, is this made by design? Or it is just an artifact
of the parser (as I don't remember people write code like them)?
