I started reading some of in-Til written source code and immediately asked myself why do we need:

1. proc p (name) { ... } instead of simpler proc p name { ... }
2. if ($msg == "QUIT") {break} instead of simpler if $msg == "QUIT" {break}
3. only the verbose construction of a dict set d1 [dict.create (a "alfa") (b "beta") (c "gama")] instead of providing a second "constructor" set d1 [dict.create2 a "alfa" b "beta" c "gama"]
4. the verbose math ($x * $y) instead of math $x * $y

Looking into this further both points (1) and (2) are actually similar to "set destructuring a simplelist" (set a b c (1 2 3)).
