that really works!, so looks the key here is
1) use <expr> as you mentioned,
2) use ":" . func()
3) return the command string from the func

great to learn!

this also works, but
it seems the exec helps to
1) evaluate the expression, but also
2) execute the result right away.
is there a way to evaluate the express (1) , but not to "execute"
them(2) , in "command" ?

none of these works...
command! -nargs=* MyGit call MyGit(<q-args>)
command! -nargs=* MyGit eval(":" . MyGit(<q-args>))
