from this bird eye perspective (and without knowing the details of your scenario), you might want to consider avoiding the [eval] overhead by using the {*} operator in 8.5+ for the boxing case ...
(t.003 is a kind of baseline measurement and appears slightly more expensive because the values in the argument vector must be turned into Tcl_Objs first etc., a conversion which has already been achieved if dealing with a [list] and its values).
Thank you for this example. I forgot to mention that my application will, in some cases, create argument list that may be long (few thousand integer values). I expect it to handle up to 7200 values that are integers (2 digits maximum). Is it a bad idea to expand that list and pass 7200 arguments to init?
In this example it appears that it is actually better to expend the list using {*}, than to pass it as a value?
Best regards,
