Maybe it's not a big deal. But these are the deals that end up making things go faster I > think.

Which one ? I am used to using "xxx" but if 'xxx' is more efficient, I can use it > instead (when both are semantically equivalent). 'xxx' is faster a bit at parse, just an int comparison per byte.

This may have big memory impacts, specially if the stack frame also holds references to large object. For sure it > does not hurt to do some xxx=nil when xxx is not usefull anymore. Proc doesn't hold each stack, Thread does. About an orphan Proc from dead Thread, the stack may be discardable. > 3) type induction > One day the "dynamic typing" versus "static typing" language war will be over.

That means that many operations then do not need to copy the string anymore (you update > 'an_offset' and/or 'a_size' instead, still referencing the same 'string_representation').

Shugo Maeda had made a patch, but it's left yet due to the impact on the external interface mainly. > 5) Cache. > Reading the books about the implementation of Smalltalk gives some hints on how much efficient such caches can > be.

You can add instance variables on the fly, the last assumption may not be correct. I considered it too, but had no good idea. > A less trivial cache is for inlining small methods.

Maybe, but it may prohibit/restrict forward reference, or gain compile time cost much. -- Nobu Nakada
