 * Date:    29 Oct 2002
 * SUMMARY: Testing "use" and "set" operations on expressions like a[i][j][k]
 * See http://bugzilla.mozilla.org/show_bug.cgi?id=96526#c52
 *
 * Brendan: "The idea is to cover all the 'use' and 'set' (as in modify)
 * operations you can do on an expression like a[i][j][k], including variations
 * where you replace |a| with arguments (literally) and |i| with 0, 1, 2, etc.
 * (to hit the optimization for arguments[0]... that uses JSOP_ARGSUB)."
