#22 Problem when command substitution with redirection

[Koichi Nakashima]

Using Schily Tools 2020-06-09 on Debian 10.4.

$ bosh -c 'var=$({ echo value >&3; } 3>&1)'
bosh: 3: bad file number

Could you please check the attached patch?

I am however not sure whether this is the final solution, as there is no binary node element for { ...;} grouping and other cases could also miss the {} when a back translation from a binary syntax tree into text happens.

This back translation is used in the recursive parser for $()...

Hi, two days ago it did not work to add the attachment, now it has been added to the previous post.

Oh, I'm sorry. I forgot to check this ticket.

It seems to work in the simple case above. However, please note that I have not tried it in complicated cases.
