Ruby 1.9.3 syntax for block as argument

Question

So in Ruby 1.9.2-p290 I can do this

content_for :something, do    
end

which is quite nice. But that's a syntax error in Ruby 1.9.3-p125 and instead I need to do this

content_for(:something) do
end

Where can I find documentation about this syntax restriction? Is there any other way it could be written in 1.9.3-p125?

Answer 1

Just remove the comma:

content_for :something do    
end
