^ Struct creates non-standard classes
179532 [r.mark.volkm] If Struct is a shorthand way for creating Classes, why don't objects
+ 179536 [david vallne] My guess is because Struct directly accesses a C hashtable, instead of
| 179543 [r.mark.volkm] My issue is that I wanted to think of Struct as an alternate way ofdefining a class and that after doing so I could use it like any otherclass. However, classes created using Struct aren't the same asclasses created in the "normal" way and because of that I have toremember when I use them how they differ. I've found one way in whichthey differ and don't know if there are others.
| + 179554 [shortcutter ] You can.
| | + 179592 [david vallne] Amen.
| | + 179654 [hal9000 hype] Well, what if you want to add a new method to the class? That

| |   179660 [hal9000 hype] It doesn't have to, but it's common practice.
| |   179705 [david vallne] Hmm. Can you give an example where you absolutely need to access an instance
| |   179728 [r.mark.volkm] I think the main use would be for writing tools that help Rubydevelopers. For example, I might want to write a tool that inspectsRuby objects in a running program. I might want to ask "What data doesthis object hold?". In order to answer that question, I'd have to knowwhether the object was created from a "normal" class or a struct.

^ Implanting a new method for a class
179541 [jeppe88 gmai] class Array. I would like to write a ruby file that sums all of the digits
+ 179555 [levin grunde] You are confusing classes and instances of classes.  You are definingmethods for the Array class, not for actual array instances.
| 179561 [jeppe88 gmai] Thank you, for sorting things out for me :)
+ 179557 [klancaster19] Jeppe,

^ Equivalent of const modifier
179563 [eastcoastcod] Very often, I'd like to ensure (and document) that a method will not

^ Howto use rubyscript2exe to package some external application along with ruby
179593 [Nuralanur ao] Dear all,
+ 179594 [david vallne] I have very, very strong doubts rubyscript2exe will detect and pack external
+ 179602 [alex deletem] No, it's not done automatically. You can tell rubyscript2exe to include an external executable in the package by setting the constant RUBYSCRIPT2EXE_BIN at "compile"
