Editing Variadic function (section)

===In Tcl===
A [[Tcl]] procedure or lambda is variadic when its last argument is {{code|args}}: this will contain a list (possibly empty) of all the remaining arguments. This pattern is common in many other procedure-like methods.<ref>{{cite web |title=proc manual page |url=https://www.tcl.tk/man/tcl/TclCmd/proc.html |website=Tcl/Tk Documentation}}</ref><ref>{{cite web |title=args |url=https://wiki.tcl-lang.org/page/args |website=Tcler's Wiki}}</ref>

<syntaxhighlight lang="tcl">
proc greet {timeOfTheDay args} {
    puts "Looks like we have [llength $args] people"

    foreach name $args {
        puts "Hello $name, good $timeOfTheDay"
    }
}

greet "morning" "Joseph" "Clara" "William" "Maria"

# Output:
# Looks like we have 4 people
# Hello Joseph, good morning
# Hello Clara, good morning
# Hello William, good morning
# Hello Maria, good morning
