No, you would not.  256 code points are not enough.

Use argv[-1], as Shanti Rao pointed out, to get the function object 
being dispatched.  That object has 2 reserved slots, in which you can 
store private data (JS_Get/SetReservedSlot).  This is what XPConnect 
does (see http://lxr.mozilla.org/mozilla/search?string=JS_SetReservedSlot).
