1) USE A REAL PROGRAMMING LANGUAGE.
2) Or use bash's "declare -n" (almost-like-a-nameref) syntax.
2a) Realize how bad "declare -n" actually is. How it doesn't avoid the
fundamental name conflict problem.

2b) => USE A REAL PROGRAMMING LANGUAGE.
3) Or redesign your code so that you don't need to pass an associative
array to a function by reference, since bash can't actually do that.
4) Or try that god-damned HACK that two people have posted.
4a) Realize how bad the god-damned HACK actually is. How it doesn't
avoid the fundamental name conflict problem (in addition to being
a million-monkey feces-fling that just happens to not blow up in
the current versions of bash).
4b) => USE A REAL PROGRAMMING LANGUAGE.
