Blocks in Procs?

  193260 [halostatue@g] The gateway is currently gone, as I understand it, because the
  193262 [khaines@en g] It's something that I am probably willing to run, if there is a news provider

Capturing stdout
193205 [damphyr@fr e] I have code that prints to stdout (using puts and/or print).
+ 193207 [shortcutter@] You can use popen but then your code is in another process.
| + 193208 [shortcutter@] ...
| + 193213 [damphyr@fr e] Yes, but I can change Kernel#puts :)
|   + 193216 [shortcutter@] You can use a simple mock method for this. See
|   + 193218 [dharple@ge e] require 'stringio'
|     + 193219 [r.mark.volkm] Here's another alternative.

|     |   193301 [uncutstone@s] IMHO, by using StringIO, you pay for something useless in this case but
|     |   193312 [drbrain@se m] You're confusing unused with useless.  I almost never use Hash#index
|     |   193317 [r.mark.volkm] You don't have to add a puts method to the String object in order to
|     |   + 193351 [uncutstone@s] Yes, print does the same.
|     |   + 193354 [drbrain@se m] The Kernel methods have this behavior, yes, but this is not a general
|     + 193220 [uncutstone@s] I am wondering whether Ruby has something similar to C++ stringstream,

Method name
193214 [Michael_ee@y] I'm looking around, but I didn't find a replacement for c++
193223 [r.mark.volkm] I assume you mean the name of the current method.  Here's one way.
193250 [dave@bu t. d] Does this work?
193284 [uncutstone@s] What if I am at the outmost level?
193293 [miken700@ya ] It seems to work properly for me on the outermost level.

| 193626 [agorilla@gm ] Converted to a case statement (because I needed a break from work).

Module, class and methods confusion
193235 [patrick@pk p] I have a test harness script that requires module "mhiqErrorLogger".
193240 [rmagick@gm i] Just a guess, but should that be
