If you want to get «x» as your $1 argument and have the callee see
«foo='x'» as its argument, you can do this:

    progfunc() { program "foo='$1'" }

Or this:

    progfunc() { program "foo=${(q)1}" }

If that doesn't answer your question, then please clarify it.

«"foo'$bar"» does interpolate $bar as a variable, despite the single
quote in there, because the ' is literal (part of the string data).
«"foo"'$bar'» doesn't, because the ' is syntactical.
