Hello all,

This is a summary of ruby-dev mailing list last week.


[ruby-dev:20441] [New Block] Who should raise warning?

  Shin-ichiro HARA suggested that the warning in the example below
  should raise at line 4, when function foo () is called.
  
     1: def foo
     2:   yield (1, 2)
     3: end
     4: foo do |x|
     5:   p x
     6: end
  
     #-> test.rb:2: warning: multiple values for a block parameter (2 for 1)
  
  Nobu Nakada gave us an idea to improve the warning like following:
 
    #-> test.rb:4: warning: multiple values for a block parameter (2 for 1)
        from test.rb:2
        [1, 2]

  Matz accepted it and Nobu commited the code.


[ruby-dev:20392] [BigDecimal] proposal to change specification   
[ruby-dev:20447] [BigDecimal] renaming proposal

 Tadashi Saito requested some changes for BigDecimal library:

  1) Adding BigDecimal#** as an alias for BigDecimal#power
  2) Remove inconsistency between BigDecimal#infinite? and 
     Float#infinite?
  3) Remove inconsistency between BigDecimal#nonzero? and
     Numeric
  4) Changing method names such as:
       * BigDecimal#sign -> BigDecimal#attribute
       * BigDecimal#to_parts -> BigDecimal#split
       * BigDecimal::E(n) -> BigDecimal::e(n)
       * BigDecimal::PI(n) => BigDecimal::pi(n)
  5) Remove BigDecimal#assign

 Shigeo Kobayashi, the author of the library, accepted the request
 but pointed out the migration problem for scripts using old method
 names.  Matz recommended us to use 1.8.0 migration as a oppotunity
 for the changes.

 FYI, You can see the current specification of the BigDecimal library from:
