well, the problem is not that the method name has special
characters, but that what you're using is just syntactic sugar for
that particular method name. it works perfectly fine when you use
the regular syntax:

  c.[](:k) { 'foo' }  # pretty ugly, eh? ;-)
  c.get(:k) { 'foo' }

alternatively, you could pass in a proc argument like this:

  c[:k, lambda { 'foo' }]

but you'd have to change your code to take that into account.
