Bug #9623: warning: "named capture conflicts a local variable" does not allow loops with named captures

Given the following example:

args = []

remaining = 'a,b,c'

begin
  /(?<token>[^,]*),?(?<remaining>.*)/ =~ remaining

  args << token
end until remaining.empty?

p args

Gives a warning with -w: test.rb:6: warning: named capture conflicts a local variable - remaining

I'm unsure if the warning is useful here. Reassigning in the loop through the named captures seems clearer than using the regexp globals.
