Hi,

In ruby 1.8.7 this does not work (syntax error):

class A

def test=(val, &block)  
end

end

A.new.test = 10 do  
end

I would really like to an associate a block in this way. Is there a way  
round this?

Cheers,  
James

Whoaa… never do it this way, and it seems doesn’t work in 1.9 too  
and I agree with you, that it should works. Ruby’s bug ??

Thanks for checking this. I guess I should raise a bug report.

I’m pretty sure this is not a bug. It’s been discussed once or twice  
before on the ruby-talk list.

What are you trying to do with this syntax? Note the potential for  
ambiguity:

A.new.test = [1,2,3].find do |i| i\>1 end

This is currently parsed as

A.new.test = (  
[1,2,3].find do |i| i\>1 end  
)

I don’t think so. It isn’t parsed as a normal method call, its parsed  
as a special construct with the = that is converted into a method call  
in a way which doesn’t support picking up a block. I don’t really  
think that using = this way would be a good idea even if you could.

If I see this

foo.bar = x do  
something  
end

I assume that “foo.bar” becomes the result of evaluating “x do …  
end”. And the Ruby interpreter does so, too. Joel is absolutely  
right about the ambiguity. Note also that this it is not possible to  
somehow make a block work with a “regular” assignment (i.e. a direct  
variable assignment):

bar = x do  
something  
end

Again, x will be called with the block and the result will be assigned  
to bar. It would be a very bad idea IMHO to introduce inconsistencies  
here. Please rather try to find a different solution. Note that you  
can always do

def bar(&b)  
@block = b  
end

And then

foo.bar do  
something  
end

Kind regards
