Yeah, it is weird. A better (?) function illustrating the problem is function q; echo $argv;sleep $argv;echo $argv;end q 10s&; q 3s&;q 6s& 10s 10s 3s 3s 6s 6s Job 3, “q 6s&” has ended Job 2, “q 3s&” has ended Job 1, “q 10s&” has ended
The sequence should be job 2,3,1, yet the function calls are completed in sequence (with observed delays) 10s, 3s and 6s rather than yielding 10s 3s 6s 3s 6s 10s Using ".. ;and ... ;and ... &" to join statements would still only process the last command in background and not the block of commands - yielding results similar to above.
