The 'subshell' inherits everything from the main shell.
This was fixed a few years ago (look at the CVS history for eval.c).

For another one, how about:
	(exit 3); eval echo $(echo \$?)

netbsd 'sh' outputs 0, but pdksh outputs 3.

The version I'm playing with now treats `...` differently from $(...)
