Ruby double pipe assignment with block/proc/lambda?

ruby syntax operators variable-assignment block

You can use begin..end:

@foo ||= begin  # any statements hereend

or perhaps consider factoring the contents of the block into a separate method.

ruby syntax operators variable-assignment block

I usually write it like this:

@foo ||= (  myobject.attr = new_val  myobject.other_attr = other_new_val  myobject.bar(args))

ruby syntax operators variable-assignment block

@foo ||= unless @foo  myobject.attr = new_val  myobject.other_attr = other_new_val  myobject.bar(args)end
