SKILL equivalent of TCL "splatter" operator

liorscotland

Hello all. Let us assume the we have a list list1, of 2 elements. I need to feed those 2 elements as separate arguments to a proc, say proc1.
What that I would do in skill is:
proc1(   car(list1) cadr( list2  )
In TCL, I would do this:
proc1 [ lindex $list1 0] [lindex $list1 1]
or... Us the splatter operator:
proc1 {*}$list1
Naturally, the 2nd way is easier, and scalable, whereas the 1st way is not scalable, if proc1 can accept an arbitrary number of arguments.
Is there a way to achieve the same in SKILL?
Thanks.

    Hi Lior,

    I'm only teasing ;-)

    Obviously big languages like Tcl have the benefit of many more resources (such as stackoverflow) which help to answer such questions. However, this is one of those things that require your muscle memory to be trained when you're using a language - then they become natural.

    That said, a google search for "skill call function with list of arguments" finds (a handful of hits down) one of Jim's blogs

    which mentions apply for this - in fact it's covered in more detail in part 1 (linked to from that, of course) which also leads to this general Wikipedia reference as apply is used in many languages based on lambda calculus.

    What's even more amusing is the reference to Tcl on that wikipedia page:
