Wouldnʼt it be easier to define a macro to do the
`command-line-args-left' handling on behalf of a defun? That macro
would then consume any args up to the next arg starting with '-', so
you could do

emacs --function foo arg1 arg2 arg3 --function bar arg4 arg5 arg6

There are also quoting and conversion issues to think about, eg:

emacs --function foo hello 3 indent-tabs-mode 'always

Do we make people say

"hello" if they want strings, which implies that indent-tabs-mode
would be treated as a variable, 3 as a number, and the ' needs to be
escaped somehow?
