 #### Performance
+- define is one of most frequent callee, when in scope with very few vars, lookup sequentially
 - push_back - repeatedly without reserving size
 - range - with for(int i...) and reserving result size can be 3times faster on (range 1 10000)
 - mini_sprintf - unnecesary copying between vector and list
-- (do ..) repeatedly assign to acc, maybe somewhere else
+- (do, scope ..) repeatedly assign to acc
