Can ruby comment out a block of code?

Ruby

It sounds pretty stupid, but I could not find a way to do it in Ruby
yet.

Such in C/C++/Java:
/*

Am I missing something???

Help, please!

Ruby’s block comment looks like this:

=begin

We’re in a comment here. Both the =begin and the =end must be the
first elements on a line for this to work.

=end

$ acroread Programming\ Ruby.pdf

Search for =begin

Page 218:
</do this>

Looks like a line starting with “=begin” and a line starting with “=end”
will comment out a chunk of code.

Are there any plans on introducing shorter form in ruby 2?

The form isn’t that much of a problem, but the fact that something like
that isn’t possible

puts “hey” =begin
comment
=end

Using all pound signs is more common - I only see the =begin / =end
style for file headers. Just Learn To Use Your IDE/Editor, and use
whicheverkeycombo it provides for line-commenting a paragraph, and
letting you span such a comment over multiple lines easily. I -think-
ruby-mode for Emacs supports auto-fill for that. Might be thinking of
another language though.
