I do not think we need to do anything for arbitrary expressions.
The proposal so far was just to handle a function call wrapped
around something else by converting to the function name followed
by whatever we'd emit for the something else. You cannot realistically
handle, say, operator expressions without emitting names that will
require quoting, which doesn't seem attractive.
And no, deduplication isn't on the table at all here.
