I want to keep running gsub! on a string until it returns nil. How do
you prefer to do this?
true while str.gsub!( ... )
while str.gsub!( ... ); end
begin
done = !str.gsub!( ... )
end until done
begin
made_replacement = str.gsub!( ... )
end while made_replacement
...some other way?
I would use:
while str.gsub!( ... ); end
"block ... while" is a 'regretted' feature
(http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/6768\).

Proper devotion to symmetry leads us to the knowledge that the
sacred bang character must always be paired.
until !str.gsub!( ... ); end

loop { break if str.gsub!(...).nil? }
because it clearly expresses the idea of "keep running gsub! on a string until it returns nil".

Less prolix:
0 while str.gsub!( ... )

a = "bccccce"
begin
callcc{|@a|}
a.gsub!(/bc/,"cb") or raise nil
@a.call
rescue
puts a
end
What else, threads maybe

we can deny everything, except that we have the possibility of being better. simply reflect on that.

Having been *gotten* accustomed to the
while (!expr) {
do_this();
}
way of writing things, I would probably use this in ruby:
until str.gsub!( ... ) end
Generally, I write what ever I feel works when I am testing. The try to refine
it into as clear and concise a manor as I can before I finish the prototype.

Sorry, I meant

I wouldn't worry; the first version isn't exactly "War and Peace" 
I dislike the throwaway nature of both of them anyway.
