also Tcl is sort of like that but inside out:

  set i 3; set j 4; puts "[expr $i+2] [expr $i*($j+1)]"

but then some lisp-weirdos define Tcl procs for + * etc, resulting in:

  set i 3; set j 4; puts "[+ $i 2] [* $i [+ $j 1]]"

i think i recall jMax2 had it like:

  [var i: 3]
  [var j: 4]

  [list ($i+2) ($i*($j+1)) }
   |
  [print]

and similarly with $1 $2 instead of $i $j

(but jMax4 had a different sin-tax that I don't even recall.)
