Hi all,
This might sound a bit wierd but I would like to know if
there are any other ways of calling a method without using . operator or
calling send().
Is it possible using blocks or something else?

(or __send__ presumably). How about this one?
def foo
puts "hello"
end
m = method(:foo)
m
What are you trying to achieve anyway?

You could write a DSL that would make it look like you weren't doing dot or
send() but at some level you're going have to use one of those, or maybe
instance_eval. e.g.:
objects = {
:foo => foo_object
}
def method_missing(name, method)
objects[name.to_sym].__send__(method)
end
# calls foo_object.bar_method
foo_object :bar_method
It might be helpful if we knew the problem you're trying to solve -- can you
give us any more info?

Look Ma, no dots!
class Foo
def hello
puts "hello!"
end
end
eval "Foo\056new\056hello"
#=> hello!
I will send my contact info via email so that I may receive my prize.

objects[name.to_sym].__send__(method)
end# calls foo_object.bar_method
foo_object :bar_method
Correction: final line should have been
foo :bar_method

No meta programming needed
irb(main):001:0> "foo".instance_eval { puts length }
3
=> nil
Cheers

One more way uses colons:
a = [1,2]
a::length # => 2
a::push(3) # => [1,2,3]
a::length # => 3
