It's a return in a subshell in a function, i don't think the
comparison is far fetched.
I see what you mean,  but that raises the question of what's a valid context.
Should we make a special case if the subshell is the "outer" compound
command of a function?

The same thing with by break and continue example:

while :;do ( while :;do break 2; done);echo foo;done

Should this raise an error? is the break in a loop context? what's a
loop context?
