dict makes named parameters easy.
proc example {a b args} {
if {[llength $args] == 1} {
set args [lindex $args 0] ;# work with unexpanded args
}
# establish defaults
set args [dict merge {default value} $args]
# use elements from dict
fn [dict get $args parameter]
# (dangerously) use args dict as variables
dict with $args {}
