multi-def docs?

I thought Ruby allows you to define similar functions in parallel by
putting the parts that differ together in square brackets. Is there
some online documentation for that? I haven't been able to find it yet.

If you mean something like this:

some_method(arg1, arg2[, arg3[, arg4]]) => nil

It is just a documentation convention to indicate
optional arguments. In RDoc files this only appears
in methods defined in C because the call sequence
is entered manually in the doc rather than being
extracted from the code itself like with pure-Ruby.

I have never heard of such a feature. This is certainly not in the core
language. Maybe some extension or framework? How do you think does the
syntax look like?

Kind regards

What follows is only approximately like what you are describing. Maybe it
will give you some ideas:

#!/usr/bin/ruby

class Demo
def initialize
@op_hash = {
"+" => Proc.new { |y,x| y + x },
"-" => Proc.new { |y,x| y - x },
"*" => Proc.new { |y,x| y * x },
"/" => Proc.new { |y,x| y / x }
}
end

def perform(y,x,m)
@op_hash[m].call(y,x)
end
end

demo = Demo.new

puts demo.perform(1.0,3.0,"/")

Output: 0.333333333333333

Sorry. Must be another language.

No, it's something else.

Thanks for the help.

Must have been a rerun then, the next new episode won't be broadcast
until next week.

No it wasn't. Game 6 of the WS was on Thursday. The new episode of
Fringe was postponed to next week. That's what the commercial in the
link in the OP was about.

What Tom Cruise show? This is the 2nd mention I've seen of it, but I
don't know what it refers to.

I think it's Canadian TV? I've seen it mentioned before too, but don't
know if it's a real show or just a joke.
