Use tee + process substitution to split STDOUT to multiple commands

some_command | tee >(command1) >(command2) >(command3) ... | command4
Using process substitution, we can 'trick' tee into sending a command's STDOUT to an arbitrary number of commands. The last command (command4) in this example will get its input from the pipe.
Sample Output
$ echo foo | tee >(cat) >(cat) >(cat) | cat
foo
foo
foo
foo

That one doesn't work for me, it is not portable: /bin/mksh: syntax error: '(' unexpected
