For example, for i in $(seq 10); do blah blah blah; done cannot be rewritten as exec for i in $(seq 10); do blah blah blah; done This is _not_ limited to when the first word is a reserved word. Figuring out when you can add exec is not possible outside the shell itself. Therefore I think the best solution would be if shell's had -o exec-when-possible, that dmenu could start the shell with. This there something like this? This would be useful for system(3) too.
