"Crystallizing" Objects

[Robert Klemme]

[growinghash.rb]require 'delegate'

class GrowingHash < DelegateClass(Hash)
def initialize(*a,&b)
super(Hash === a[0] ? a[0] : Hash.new(*a,&b))
end

def store(k,v)
raise ArgumentError, "Key already set: #{k.inspect}" if key? k
super
end

alias []= store

def set_if_unset(k,v=nil)
store(k, block_given? ? yield : v) unless key? k
end
end

Is this intended to be thread-safe?

Of course not. (see my posting)

Kind regards

Ah, forgive my confusion then.
