Well, the feature in question (syntactically sugary closures) is in Smalltalk
and (therefore) Ruby, both of which have class. (Or, at least, classes.)
I imagine Perl adopted it from there.
I'm personally a fan of any syntax that makes abstraction easier to type.
Lua: function () return foo + bar end
Smalltalk: [ foo + bar ]
