Open Change Requests
====================
#U001 cut operator for short-circuiting method chains
purpose would be to prevent nil returns during method chaining, would break 
the chain rather than return nil down the chain
posted to ruby-talk 02/13/01 [ruby-talk:10804]


#U002 new proper name for Hash#indexes, Array#indexes
I'm unsure of whether matz has settled on a name or not.
posted to ruby-talk 02/14/01 [ruby-talk:10830]


#U003 infix 'function composition' operator
purpose is to allow chaining proc's
posted to ruby-talk 02/14/01 [ruby-talk:10837]


#U004 More list operators
wants more list operators in Ruby, like those found in languages such
as Haskell, Lisp, Prolog, Icon, and Erlang
posted to wiki:RubyWishList(obsolete)


#U005 Discuss possibility of icon-like suspend or "inside-out yield"
This is used to create generators rather than iterators. It is achieved by 
leaving the state of the function on the stack.
posted to wiki:RubyWishList(obsolete)


#U006 Alternate variable declaration
like "my" in perl, a way of telling Ruby that I don't care if there is 
already something in scope called foo, this foo is private.
posted to ruby-talk 02/16/01 [ruby-talk:10975] [ruby-talk:10990]


#U007 Pragma to disallow variable creation with just an assignment
ala perl's 'use strict "vars"'.  Would disallow variable creation by mere 
assignment.
posted to ruby-talk 02/16/01 [ruby-talk:10975] [ruby-talk:10990]


#U008 Keep track of implicitly called methods
ala perl's 'use strict "subs'.  keep track of what methods have been 
implicitly called and have a function you can call that checks that they all 
resolve properly.
posted to ruby-talk 02/16/01 [ruby-talk:10975] [ruby-talk:10990]


#U009 Allow "#{foo} bar" to be used as "#foo bar"
allow simple interpolations to use shorthand #foo rather than #{foo}
posted to ruby-talk 02/16/01 [ruby-talk:10990]


#U010 new method Enumerable#hashify(value)
Return a hash based on iterating through the receiver (an enumerable), 
either setting every value to the parameter "value" or setting the values 
via a block.
posted to ruby-talk 02/20/01 [ruby-talk:11195]


#U011 Add a method: Time#set(seconds <,microseconds)
This method, which is much like Time.at, will alter an existing Time object.
