This makes me feel like I'm reading Perl code, where everything is a
mass of strange, unconventional operators. Inventing new, unfamiliar
operators for a language has its place ... but this just feels contrived,
where typical += operators are what's really wanted.

This is inviting unreadable code, where you have to keep looking back
and forth and counting to figure out what each number in an expression
means. I've adjusted enough Perl expressions after changing a regexp
to call it a maintenance nightmare, too.
