When reading multiple arguments {1} {2} it would be nice if you could easily access each argument in a simple way. E.g. as @arg

{= if($arg[1] gt $arg[2]) { $arg[1]++ } =}

Problem:

If $arg[1] changed, should $_ be recomputed?

What if both are changed:

{= if($arg[1] gt $arg[2]) { $arg[1]++; $_.="ged" } =}
