dtrace discuss - Apr 2007 - requiring array indices be int64_t

With dtrace, I can use function arguments in the form of
arg0, arg1, etc, as indices into an "associative" array.

If all that an array takes as an index is an int64_t, is there
any reason for dtrace to require me to have an explicit type
conversion in there rather than having it do it for me
automatically?

At present I need to do:
mblks[arg0]
or
mblks[(int64_t)((mblk_t *)arg0)->b_cont]

whereas what I''d like to be able to do is:
mblks[arg0]
and
mblks[((mblks_t *)arg0)->b_cont]

and have dtrace worry about what b_cont needs to be
transformed into in order for that to work.

Use args[0] instead.
