yes. `() can contain only words, not things like redirections and pipes,
whereas `{} can contain any rc commands. that `() works is just a happy
accident of the orthogonality of rc.

Happy New Year to everyone!
Is there a "real" difference between
; x = `{prog args ...}
and
; x = `(prog args ...)
The only difference in the text of the commands is
braces versus parenthesis.
Both conform to the syntax, and I cannot get them to produce
different results.
Does anyone have any opinions when one is preferable to another?
