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