Perl: Sort List, Matrix, Object

Syntax = Most Important Aspect of a Programing Language

the quality of a programing language, can be judged by how much of it can be explained by its syntax alone.

with this criterion, the order are roughly: Mathematica ≻ PHP ≻ Lisp ≻ JavaScript ≻ Ruby? ≻ Perl ≻ Python ≻ Java.

this is also the most important criterion in judging a language.

If you have coded one of {Haskell, ML/OCaml/F#, erlang, Scala, Pascal/Ada, Lua, tcl, APL, SmallTalk, PostScript}, i'd be interested in your opinion on their placement in the above. (you should have coded in the lang for a few years)
