Actually, statements with "the best way" in them rarely are,  
especially if they start with "Actually".

In this case, the best way to actually get a change into the system is  
indeed to submit a patch to ruby-core. You're more than welcome to set  
up the system you're talking about. Until then it is simply pie-in-the- 
sky.

Error in MatchData docs

Hello,

I wanted to point out an error I found in the documentation for the
MatchData class, visible at
http://ruby-doc.org/core/classes/MatchData.html .  Please advise if I
should post this elsewhere (such as a bug tracker).

Under the heading "mtch.captures => array", that page says:

    Returns the array of captures; equivalent to mtch.to_a. 

However, that is demonstrably not the case, at least in Ruby 1.8.5.
MatchData#captures is different from MatchData#to_a in that to_a's first
element is the entire matched string, as in:

    irb(main):001:0> /(.)(.)(.)/.match('abc').captures
    => ["a", "b", "c"]
    irb(main):002:0> /(.)(.)(.)/.match('abc').to_a
    => ["abc", "a", "b", "c"]
    irb(main):003:0>

I suggest the verbage be changed to append the text "except that to_a
inserts the matched string as the first array element" after "equivalent
to mtch.to_a".

Using a single Rake dependency block to generate more than one file.

Often I have a block that generates more than one file.   Although  
Rake seems to accept reasonable syntax for doing this it doesn't   
work.  Here's a complete but simple example:

require 'rake'

a = 'file1.txt'
b = 'file2.txt'
file [a, b] do
   `touch #{a}`
   `touch #{b}`
end

task :all => [a, b]

Although Rake excepts this syntax, it doesn't do what I'd expect.  It  
gives me the surprising answer that it doesn't know how to build  
file1.txt even though it really should know.   I realize I could copy  
the block or define a function for it and use multiple file  
dependency declarations but this seems really clumsy and not very  
DRY.  Also, while such a workaround appears to work on my platform  
there isn't any reason to believe that it shouldn't call those blocks  
twice.  The fact that it doesn't makes me think Rake is checking file  
creation too often, i.e., before it could reasonably expect a file  
exists.  Am I correct about all this?

[PATCH] File class documentation hidden by ftools.rb

Hello,

"ri File" gives the documentation from lib/ftools.rb and not the intended 
description of the File class.

ftools.rb has a declaration of the File class, which I suppose is not 
needed, so I removed it (attached patch). This fixes the documentation 
issues.

All 1.8 branches are affected. trunk is not (ftools.rb was removed).

Regards,
Lars
