I applaud ubuntu's efforts of trying to use smaller shell.
Really. bash is too big for any sensible embedded system.

Unfortunately it means that fixing just busybox's stripts
is not a solution - there are tons of other shell scripts
lying aroung.

dash should support "function". It shouldn't be too hard - 
dash already supports

do_something () {
    ...
}

It's just a matter of recognizing slightly diffeent syntax:

function do_something {
    ...
}
