I had trouble attempting to dynamically build the equivalent of the @closures array using the "map {BLOCK}" syntax - apparently that conflicts with lvalue subs. }
sub : attribtute ... will be parsed at the beginning of a statement as "sub" being a label, and attribute... the code to run. Put a + in front of sub to disambiguate. Witness: 
$ perl5.8.4 -we'sub xyzzy { print "huh?" } sub : xyzzy; shift() and go
+to "sub"' 1 2
huh?huh?huh?
