Subject: Parameter Type Checking in methods.Q?

Again...just wondering....(and you can probably tell I'm comparing Ruby
with Java/C here again, following on from the "++" discussion...)

def MyObject
  def my_method(obj)
    if obj.class!=String then raise "Wrong Type!"
    end
    ...stuff...
end
end

Would it cause problems with the general syntax to include some sugar to
rewrite this as:

...
def my_method(String obj)
end
...

Or is there any quick easy meta-programming to label methods as
expecting certain types?

Or am I being a big-baby wanting this kind of check, and I should get on
with the Dynamic Vibe of Ruby ? :)

(I just noticed that sometimes I get lost in my own programs by not
checking types thoroughly; yet Java would have forced me to stop and
think...)

John
