anonymous lists
Is there a place in es for `real' anonymous lists?
At the moment, es seems to follow rc, in that any anonymous lists
(i.e., those returned by <>{ ... } or constructed by ( ... )) in any
context other than the RHS of assignment are instantly flattened.
How about changing the semantics of:
; foo ( a b c d )
to:
; anon_list = ( a b c d ) foo anon_list
and similarly with lists returned by <>{}.
One can still flatten lists explicitly with $. I would also expect:
; foo $( a b c d )
; echo $#( a b c d )
to be the same as the current behaviour of:
; anon_list = ( a b c d ) foo $anon_list
; anon_list = ( a b c d ) echo $#anon_list
